Four Seasons In One Day... the title of a song by legedary Aussie band 'Crowded House'
Aussies living along the southern coastline of the continent understand this song implicitately.... they experience the likely most changeable weather patterns in the world. On any given Spring, Summer or Autumn day, one can experience all four seasons ( by AU stantards ) in one day. Winters ? yeah, nah, remarkably stable, but even they can alternate between clear and sunny, and a howling cold westerly blowing in from a cut off Southern Ocean low and frontal system.
So here we have 10 bi polar southern AU climes.... climate averages and data, ( which tend not to tell the full horror of the changeabilty lol ) and examples in recent years of spring/summer/autumn/winter carnage all in one day....haha.
ALBANY, WA
Climate
Albany has a warm-summer Mediterranean climate (Köppen Csb) with dry, warm summers, mild, wet winters, and pleasant springs and autumns. Summers have short spells of very hot weather, but cool ocean breeze brings relief, especially during evenings and nights. The city is situated on what is promoted as the "Rainbow Coast", an appropriate title given the frequency of days with both sun and drizzle or showers. Albany has 44.8 clear days annually.
July is the wettest month, with a long-term average of 144.0 mm (5.67 in). Rain in excess of 0.2 mm (0.01 in) occurs on two days out of every three during an average winter. The driest month is February with a mean of 22.9 mm (0.90 in).
Albany received a record amount of rain on 20 November 2008 when violent storms swept across the Great Southern region. The town was flooded after 113.8 mm (4.48 in) of rain fell in a 24-hour period, the highest amount recorded since rainfall records began in 1877. The wettest month on record was June 1920 when 292.8 mm (11.5 in) fell, while February 1877 and February 1879 remain the only rainless months.

ESPERANCE, WA
Climate
Esperance experiences a Mediterranean climate (Köppen climate classification Csb) with warm, dry summers and mild, wet winters. It is subject to wide variations in the weather, from hot summer days when northerly winds arrive from the interior of the state, to cold, wet winter days with southerly winds from the Great Southern Ocean. Annually, the town has 95.5 clear days.
Bi Polar Esperance:
EUCLA, WA
Climate
Eucla has a semi-arid climate (BSk) with Mediterranean climate (Csb) tendencies. Summers are warm and dry, although mild by Australian outback standards. However, very hot days can occur, caused by hot northerly winds from the Great Victoria Desert. Winters are mild to cool with a rainfall peak. For a semi-desert climate the humidity is rather high all-year round, due to the moisture from the nearby ocean. Despite its close proximity to the desert, the locality only gets 94.4 clear days annually, which is lower than the humid subtropical cities like Sydney and Newcastle on the east coast. With summers being right around 22 °C (72 °F) means, temperatures are near the border between maritime and subtropical climates, although Eucla is highly variable due to the combined cool-ocean and hot-desert influences.
Average maximum temperatures vary from 25 to 27 °C (77 to 81 °F) from December to March, to 18 °C (64 °F) in July. The average annual rainfall of 320.1 millimetres (12.60 in) is evenly spread through the year, with monthly totals ranging from 14.9 millimetres (0.59 in) in January to 35.0 millimetres (1.38 in) in December. The highest temperature was 49.8 °C (122 °F) on 19 December 2019, while the lowest was −2.2 °C (28 °F) on 20 June 1936.

CEDUNA, SA
Climate
Ceduna experiences a cold semi-arid climate (Köppen: BSk, Trewartha: BSbl); with warm, dry summers; mild to warm, dry springs and autumns; and mild, relatively dry winters. June is the wettest month. The average yearly precipitation is just under 300mm at the coast and diminishes northward into the interior, becoming increasingly arid. Goyder's Line, which demarcates the edge of the area where rainfall is generally sufficient to support agriculture, starts near Ceduna. On 19 December 2019, the maximum temperature of 48.9 °C was recorded.
Bi Polar Ceduna:
PORT LINCOLN, SA
Climate
Port Lincoln experiences a warm-summer Mediterranean climate (Köppen climate classification: Csb), Trewartha: Csbl), receiving just enough annual precipitation to avoid being classified as a semi-arid climate (BSh); with warm, dry summers; mild to warm relatively dry springs and autumns; and mild, winters with moderate precipitation. In January, the hottest month, temperatures average 15.8 to 26.2 °C (60.4 to 79.2 °F), while in July, the coldest month temperatures range from 7.4 to 16.1 °C (45.3 to 61.0 °F)
Winter days are cool and cloudy, with frequent light drizzle and showers. Cold fronts cause periods of heavy rain and colder temperatures in winter, and violent storms can occasionally roll in from the southern ocean. Summers are mild to warm with cool sea breezes keeping the temperatures generally below 30 °C (86.0 °F). However, on rare occasions a severe blast of heat from the deserts to the north can cause several days of temperatures well over 40 °C (104.0 °F).
Rainfall in summer is limited to very infrequent showers or thunderstorms and sometimes during summer, no rain occurs at all. Snow has never been recorded and frost is a very rare occurrence, usually happening only on clear winter nights away from the coast. Extremes have ranged from 48.3 °C (118.9 °F) to −0.3 °C (31.5 °F), while the wettest month on record was June 1981, recording 200.4 millimetres (7.9 in). Despite being somewhat dry, the town only receives 57.2 clear days annually.

MOUNT GAMBIER, SA
Climate
Mount Gambier experiences a temperate mediterranean climate, with mild, relatively dry summers with very cool nights; mild springs and autumns with moderate rainfall; and cool winters with high rainfall. July is the wettest month with an average of 100.5 mm falling on a staggering 21.9 days, whereas February normally records the lowest rainfall with an average of 26.6 mm on only 7.8 days. The highest temperature recorded in Mount Gambier was 45.9 °C on 20 December 2019 and the lowest temperature recorded was −3.9 °C on 20 June 1950 and 2 July 1960. Mount Gambier only has 40.5 clear days on an annual basis. Summers (and likewise annual mean temperatures) are cool for the latitude on account of its exposure to the prevailing westerly belt. Extreme summer minima near 0 °C (32 °F) are especially of note compared to northern hemisphere locations at a similar latitude and near the coast at sea-level.

PORT FAIRY, VIC
Climate Port Fairy has a mild Mediterranean climate (Csb) that closely borders the oceanic climate (Cfb), and is characterised by mild, dry, very swingy summers and cool, rainy winters with frequent cloud cover. Annual and especially winter rainfall is much higher than in Melbourne due to its westerly exposure.
During the heatwave in southeastern Australia, Port Fairy recorded a maximum temperature of 45.2 °C (113.4 °F) on 20th December 2019

MELBOURNE, VIC
Climate
Melbourne has a temperate oceanic climate (Köppen climate classification Cfb) with warm summers and cool winters. Melbourne is well known for its changeable weather conditions, mainly due to it being located on the boundary of hot inland areas and the cool southern ocean. This temperature differential is most pronounced in the spring and summer months and can cause strong cold fronts to form. These cold fronts can be responsible for varied forms of severe weather from gales to thunderstorms and hail, large temperature drops and heavy rain. Winters, however, are usually very stable, but rather damp and often cloudy—though not as cloudy as inland areas or places farther west like Warrnambool due to Melbourne's downwind placement relative to the prevailing westerlies, as evident by its dry winters by southern Victorian standards. The city, however, is exposed to southerly and southwesterly systems as manifested by the overcast, drizzly winters.
Port Phillip is often warmer than the surrounding oceans and/or the land mass, particularly in spring and autumn; this can set up a "bay effect", similar to the "lake effect" seen in colder climates, where showers are intensified leeward of the bay. Relatively narrow streams of heavy showers can often affect the same places (usually the eastern suburbs) for an extended period, while the rest of Melbourne and surrounds stays dry. Overall, the area around Melbourne is, owing to the rain shadow of the Otway Ranges, nonetheless drier than average for southern Victoria. Within the city and surrounds, rainfall varies widely, from around 425 mm (17 in) at Little River to 1,250 mm (49 in) on the eastern fringe at Gembrook. Melbourne receives 48.6 clear days annually. Dewpoint temperatures in the summer range from 9.5 to 11.7 °C (49.1 to 53.1 °F).
Melbourne is also prone to isolated convective showers forming when a cold pool crosses the state, especially if there is considerable daytime heating. These showers are often heavy and can include hail, squalls, and significant drops in temperature, but they often pass through very quickly with a rapid clearing trend to sunny and relatively calm weather and the temperature rising back to what it was before the shower. This can occur in the space of minutes and can be repeated many times a day, giving Melbourne a reputation for having "four seasons in one day",[98] a phrase that is part of local popular culture.[99] The lowest temperature on record is −2.8 °C (27.0 °F), on 21 July 1869.[100] The highest temperature recorded in Melbourne city was 46.4 °C (115.5 °F), on 7 February 2009.[100] While snow is occasionally seen at higher elevations in the outskirts of the city, it has not been recorded in the Central Business District since 1986.
The average temperature of the sea ranges from 14.6 °C (58.3 °F) in September to 18.8 °C (65.8 °F) in February; at Port Melbourne, the average sea temperature range is the same
