Victoria's warmest spring nights on record, second-warmest November days on record
The numbers are in for spring 2020. Daytime temperatures were much warmer than average in eastern and northern Victoria, and along the west coast. Night-time temperatures were much warmer than average across the state, and highest on record for much of eastern and central Victoria. Victoria's mean minimum temperature was 1.72 °C above the long-term average, the highest on record for spring (more than 0.2 °C higher than the previous record set in 2009). In other words, Victoria just had its warmest average spring nights on record.
Daytime temperatures were much warmer than average in most of eastern and northern Victoria, and along the west coast. The state-wide mean maximum temperature was 2.01 °C warmer than the long-term average, ranking as Victoria's equal seventh-warmest mean daytime temperature on record for spring. But it was a particularly warm end to the season; Victoria's second-warmest November on record. State-wide, the mean maximum temperature for November was 3.85 °C above the long-term monthly average. Rutherglen Research, Mildura Airport, Ouyen (Post Office), Walpeup Research and Yarrawonga all had their warmest, or equal warmest, November temperatures on record on the 28th. Ouyen reached 45.8 °C on November 28th, the highest maximum temperature in Victoria this spring.
Spring rainfall was generally close to average across most of Victoria. It was drier than average in some areas scattered across the east, and wetter than average in parts of the West Central and West Coast districts; Mortlake Racecourse and Warrnambool Airport had their highest total spring rainfall on record.
November ended up being drier than average in the north-west and most of the eastern half of Victoria but rainfall was above average in parts of the south-west and around Geelong, and close to average elsewhere.
The above average temperatures are likely to continue with warmer than average days and nights forecast for Victoria this summer (December to February). And the rain is likely to return with a wet summer outlook driven by a La Niña that is expected to peak around December or January and is likely to persist until at least the end of February 2021. Australia's temperature variability is influenced by global warming caused by human activities. Australia's climate has warmed by 1.44 ± 0.24 °C since 1910.
