Weather, Waves and Water – The New South Wales Central Coast This book fills a much-needed void in providing a specialist description of the meteorology of the New South Wales Central Coast. This is an area that has progressed enormously over the past decade, and has now become a major social and tourist hub, strategically located between Sydney and Newcastle. Fishing, boating and tourism are of major importance in the area, to both locals and to the increasingly large population of Sydneysiders who have made the Central Coast a prime holiday location. All these activities are highly weather sensitive so a discussion of the unique local meteorology of the area seems timely. Told through the turbulent story of east coast lows, shipwrecks, thunderstorms, southerly busters, floods, dust storms and bushfires, the author, Richard Whitaker, provides a focussed insight to the “Weather, Waves and Water “ of the New South Wales Central Coast. Progress in the prediction of all these types of weather events is also discussed. Richard Whitaker has been a meteorologist for more than 50 years, and has written numerous publications about the weather. He is an active local community lecturer, delivering talks about meteorology to such groups as Probus, Rotary, Libraries, U3A, bushfire brigades, historical societies, schools and business groups. He served with the Bureau of Meteorology from 1971 to 2002, and then became Chief Meteorologist with the Weather Channel and Sky News Weather from 2004 to 2016. Today he lives at Terrigal on the Central Coast with his wife of 52 years. They have two children and five grandchildren.

                                                By Richard "Dick" Whitaker


Australia’s Natural Disasters tells many stories of the devastation that nature has wreaked on our wild country and its people. From the agonies of droughts and floods to the shocks of earthquakes and bush fires, Australia is a country famed as much for its ferocious natural hazards as for its rich environment. Freak weather has caused plane crashes and shipwrecks. 

 On Christmas Eve 1974 Darwin pubs were bursting with festive people joking that ‘cyclones never hit Darwin’. Cyclone Tracy was expected to be another ‘near miss’. But in the early hours of Christmas Day the slow-moving tropical cyclone tore the city apart, with sustained winds of 200 kilometres per hour, and Darwin became another victim of nature. Cyclone Tracy is only one of the many extreme weather events that Australia has been subjected to. Australia’s Natural Disasters tells many stories of the devastation nature has wreaked on our wild country. From the agonies of droughts and floods to the shock occurrence of earthquakes and bushfires, Australia is a country famed as much for its ferocious natural hazards as it is for its rich environment. Freak weather has caused plane crashes and shipwrecks and even been blamed for the disappearance of a Prime Minister. 

 Australia’s Natural Disasters is a fascinating chronicle of the ferocity of nature and the dramatic effects it has had on this country and its people – from the mid-1800s to the seemingly more frequent extreme-weather events of the 2000s. 

 It is also a story of great progress both in weather prediction, as led by the Bureau of Meteorology - and in disaster recovery, from the work done by the various State Emergency Services and Rural Fire authorities. Australia now has a world-class system for dealing with natural disasters from early prediction to the aftermath. 

 Disasters covered include the bushfires of 2019 and 2020, Cyclone Yasi and Cyclone Tracy, The Black Saturday 2009 Bushfires and the devastation along with the Queensland Floods and the 2021 Floods, the Sydney to Hobart Yacht Race, the mass rescue at Bondi Beach, Dust Storms of 2009 and the devastating hail storm that struck Sydney's East and much more. 

 All this illustrated by on-the-spot photos of Australia’s natural disasters and their consequences.

The 1930 Melbourne Cup - Phar Lap and the Weather


One of the iconic events in Australian sporting history – the 1930 Melbourne Cup – was won by the legendary Phar Lap. This was an immensely popular win, coming as it did in the depths of the Great Depression that ravaged Australia at the time. 

The date was Tuesday 4th November 1930 and the existing photographs of the day show sunshine, a crowd in hats and coats, no umbrellas and no sign of windy conditions.

However a closer look at the meteorology surrounding the event shows that the benign weather was preceded by highly turbulent conditions, with strong winds, rain and volatile temperatures right across the previous day. With just a small change in the timings this famous Cup day could have been a very different occasion.


The Bureau of Meteorology synoptic chart for 9 am 3 November 1930 as it appeared in “The Argus” the next day.

"The synoptic chart on 3rd November shows a strong cold front near Adelaide with the close packed isobars a feature over south-eastern parts of South Australia and western Victoria. The accompanying Bureau “Notes on the Chart” were instructive: “The rapid development of a deep atmospheric depression in the eastern Bight was the outstanding feature of Monday morning’s weather. As shown by the isobaric chart the foremost half of this depression was receiving a strong flow of northerly winds from the inland areas of eastern Australia. During the day the centre of the depression moved to the eastern entrance to Bass Strait and also deepened considerably, this intensification of the disturbance being attended by northerly winds of almost gale force at many places in Victoria. Dust storms were plentiful inland and in Melbourne the dust was much in evidence, first in the coppery hue of the sky during the afternoon and later in fierce dust squalls after 7 pm, the wind reaching 44 miles an hour. Shortly after a light fall of “red” rain occurred in the city. At 9 pm the wind changed to a cool westerly, temperatures fell 10 degrees almost at once and the showers recommenced”. 

 The Bureau records show that the maximum temperature in Melbourne on Monday 3rd November was 31.3C and the next day, Melbourne Cup day, was only 17.7C. Rainfall for the 24 hours at 9 am on Cup Day was 3.6 mm and over the next 24 hours 2.5 mm was recorded. From the photographic evidence it looks as though the weather had cleared for the Cup – but the timing appeared to be a close thing.

For the record there were two horses with “weather “ names in the 1930 Melbourne Cup. 
Phar Lap is Thai for “sky flash” or lightning, and the horse that was runner up was “Second Wind”.

The Siege of Glenrowan: Ned Kelly's Last Stand

 

On Monday 28th June 1880 one of the more famous events in Australian history took place - it was the siege of Glenrowan - also known as Ned Kelly's last stand. This event continues to be discussed in detail over many platforms, but surprisingly little information is available about the weather on that day. This is an attempt to reconstruct those long-ago meteorological conditions.

The Back Story

On the early morning of Monday 28th June 1880 a party of police confronted the Australian outlaw Ned Kelly and his gang, who were holed up in the Glenrowan Inn, located in northeastern Victoria.

Just before dawn police opened fire on the gang as they stepped out onto the veranda of the Inn and the two groups exchanged gunfire for an extended period. The events that followed are now part of Australian folklore, with Ned emerging from the half light of the dawn dressed in armour plate and attacking the police.

He was eventually captured and the other gang members (Dan Kelly, Steve Hart and Joe Byrne) were killed.

One feature of the siege is seldom discussed - that of the weather. However by using available resources from the Bureau of Meteorology data base, contemporary photography, lunar tables and existing newspaper reports we can construct a reasonable estimate of the weather conditions on the morning of 28th June 1880. 

Available weather data

Rainfall:

Glenrowan lies between two much larger rural settlements - recognised as cities today - but much smaller back in 1880. Wangaratta is about 14 km to the northeast of Glenrowan, and Benalla 30 km to the southwest.

Weather observations did not commence at Benalla until 1882 - some two years after the siege. But fortunately records go back to 1868 at Wangaratta, with daily rainfall totals recorded all through until 1987 - a virtually unbroken period close to 120 years. This covered all of 1880, including of course, the day of the siege.

Temperature:

Temperatures are a more difficult issue. Rainfall data was taken from many rural locations during the 19th Century but temperature data is less common. The reasons for this are various but basically thermometers were harder to come by and more expensive to purchase than the simple rain gauge.

As far as the Glenrowan siege is concerned no temperature data was available in the immediate area but some ideas can be obtained from contemporary newspaper reports. The event was big news and reporters from major newspapers were sent to Glenrowan in the early morning of June 28. They rode on a special train that carried a police contingent tasked with confronting and subduing the gang.   

The reporters were Joseph Melvin of the Argus, George Allen of the Melbourne Daily Telegraph, John McWhirter of The Age and Francis Carrington of the Australasian Sketcher. They boarded the police train at Spencer Street Station late on Sunday night, 27th June 1880.

Newspaper Reports:

Francis Carrington later recalled that "the great speed we were going at caused the carriage to oscillate very violently. The night was intensely cold".

John McWhirter of the Age also described the scene: "The night was a splendid one, the moon shining with unusual brightness whilst the sharp frosty air caused the slightest noise in the forest beyond to be distinctly heard".

An article also appeared in the Freeman's Journal, Saturday 3rd July 1880- likely written by one of the reporters on the police train: "The night was clear and cold, the sky being almost unclouded. It was a pleasant night despite the sharpness of the temperature for the air was crisp and bracing and the sky was thickly studded with myriads of stars".

Upon reaching Benalla railway station the reporter again remarked on the night sky: "A fine large station but dimly lighted by gas. That mattered little though for by this time the moon was up, silvering with her radiance the earth and the heavens and casting a halo of glory upon the rugged and mountainous "Kelly country" - the peaks and spurs of which reared themselves ahead of us - standing out in bold relief against the cloudless sky".

These reports clearly  indicate that the early morning of 28th June was clear and cold, with local frosts likely around the Glenrowan area. Lunar tables indicate that the moon was in the "waning gibbous" phase - the first phase after full moon.

Francis Carrington also produced this sketch showing the reporters huddled together in the train carriage - again hinting at the very cold temperatures of the early morning, 28th June 1880. (State Library of Victoria)


Bureau of Meteorology rainfall data:

The daily rainfall record for Wangaratta for June 1880 reveals a wet spell before the siege. In the 24 hours ending at 9 am on 25th June 26.9 mm was recorded followed by 13.2 mm the next day. This was on top of 105.8 mm in April and 44.2 mm in May, meaning that it was likely that conditions in the bush in the surrounding area, including Glenrowan, were wet under foot on the morning of the siege.

Also, in "A Guide to Australian Bushranging - the Siege of Glenrowan Part 2", the author mentions that "Shortly after heading into the bush Ned passed out near a fallen tree. It is uncertain how long he was unconscious for but when he came to he crawled into the bush leaving his carbine and skull cap behind in the mud". 

This would indicate that there were likely puddles and mud areas around the Glenrowan Inn, due mainly to the rain event of the previous week.

Wind

There were no formal wind recordings taken from the immediate area. However during the early afternoon the Glenrowan Inn was set on fire to displace any gang members that may have still been inside. Photographs of the burning Inn were taken and the line taken by the pall of smoke gives us some idea on the wind direction at the time.


Looking at the two images (click to enlarge) it would appear that the wind was from the west/southwest - a common wind direction for Victoria during the winter months. 

Visibility

There are several newspaper references to "mist" around the Glenrowan area in the early hours of of 28th June, mostly around the time that Ned Kelly, in full armour, attacked the police from outside the Inn. 

A retrospective article in the Ararat Advertiser of 26th February 1914 recalled that "...when on the tragic morning Kelly loomed out of the mist in his armour and bullets began to fly..." 

In summary:

The weather conditions during the famous siege of Glenrowan that occurred from the early hours of 28th June 1880 until well into the afternoon have been reconstructed using data from the Bureau of Meteorology, contemporary photography, the lunar calendar and newspaper reports from the time.

From this information it is hypothesised that the pre-dawn conditions were clear, cold and frosty, with the ground wet underfoot as a result of quite substantial rain  over the previous week. Some morning mist also lay across the area. As the day progressed some cloud moved across but no rain fell.

Wind during the afternoon was likely from the west to southwest as deduced from the direction of the smoke plume produced when the Glenrowan Inn was set on fire by the police.

Hermit of the Murray River – “The Possum”

One of the most intriguing stories of the Australian bush is that of David James Jones – better known as “The Possum” who lived as a recluse along the Murray River for more than 50 years. 

 He lived outdoors for nearly all this time, travelling between several bush hideaways along the river and shunning nearly all human contact. From around 1928 until his death in 1982 he was almost a complete hermit, seldom conversing with anyone but presenting as a gentle eccentric who loved animals and performed anonymous acts of kindness to farmers in the area. These included fixing broken fences and crutching flyblown sheep, usually working at night while the farmers and their families slept. 

 From what is known of his earlier life, he was a New Zealand shearer who arrived in Australia around 1928 but could not find work in the local area around Wentworth. His solution to this problem was to walk away from society and he “went bush” - staying there for the rest of his life. 

 He lived off the land by fishing and trapping small game such as wallabies and foxes and dressed himself with discarded clothing left out for him by various station owners in the area. He lived in the wild, beautiful and primeval landscape along the Murray and Darling Rivers, particularly around the Wentworth and Renmark areas, constantly on the move between a series of hidden camps he set up along the way. 

 He travelled a lot at night, sometimes covering up to 50 kilometres at a stretch, always avoiding any townships in the area. He often swam back and forth across the Murray River, both to change camps and to avoid human contact. He reportedly slept in trees on occasion, leading to his nickname “The Possum”. 

 He had to endure the full gamut of Australian weather - blazing temperatures in summer, freezing conditions in winter, and all the floods, droughts and dust-storms that are all part of the climate of the area. In particular he had to negotiate the massive Murray River floods of 1956 when widespread inundation affected much of “Possum Country”, including Mannum, Mildura, Renmark and Wentworth.

From the late 1970’s those who new of him became increasingly concerned for his welfare, as it became inevitable that his advancing age would collide with his primitive lifestyle. And that day arrived in 1982 when his body was found, alone in the bush, by two woodcutters near Ned’s Corner Station (about 70 km west of Mildura) on 4th August. It was estimated that he had died some three weeks before, about mid to late July. He was 81 years of age.

On his simple tombstone is engraved:

“Possum” 1901-1982 
At rest where he roamed 

Living to that age under the harsh circumstances of his everyday life was quite remarkable. However it may have been more than old age that finally caused his death - the weather may well have been a factor. 

 For 1982 was an infamous year in the meteorological history of Australia. It saw the combined and in-phase influence of four major climate phenomena – El Nino, Indian Ocean Dipole, Inter-Decadal Pacific Oscillation and Southern Annular Mode. 

Verdon-Kidd and Kiem (*) noted that in 1982 “all four modes were locked into their dry phase” resulting in one of the most intense droughts in Australia’s recorded history. This would eventually lead into the devastating Ash Wednesday bushfires of February 1983.

In times of drought clear skies are more frequent than normal and during the winter months over inland areas this means plummeting overnight temperatures and a direct consequence – that of frost - often follows. June and July 1982 were exceptionally cold months along the Murray River, as revealed by the temperature record from the Bureau of Meteorology’s weather station at Mildura Airport (AP). This station opened up in 1946, replacing the old site at the Mildura Post Office that operated between 1889 and 1949. The AP station has taken continuous records ever since, including rainfall, temperature, humidity and wind data. It is likely “The Possum” saw aircraft taking off and landing from the airport as he passed by along the Murray River, about 8 km to the north. 

The mean minimum temperature for June 1982 at Mildura AP was 2.2C, still the coldest June on record there. For July it was only 1.5C – the coldest July on record and indeed the coldest of any month so far recorded at Mildura AP. In June below zero minimum temperatures were reported on nine occasions and in July, seven. There were many cold frosty mornings across the general area during this time. On the 21st July the mercury fell to minus 4.0C – the coldest temperature ever recorded at Mildura Airport. 

It is possible, perhaps even likely, that this succession of extreme minima were too much for “The Possum”, and directly contributed to his death.
