Adelaideans have been treated to late-season warmth this week and today was no exception.

The maximum temperature so far today for Adelaide (West Terrace) has been 28.2°C which is 6 degrees warmer than Adelaide's average maximum temperature for the month of April. The previous four days were also unseasonably warm with the following maximum temperatures recorded: 

• 30.5°C on Tuesday, 21 April 
• 29.3°C on Wednesday, 22 April
• 29.7°C on Thursday, 23 April 
• 28.6°C on Friday, 24 April 

With an average maximum temperature of 29.48°C across those four days, this was Adelaide's warmest 4-day spell so late in the season since 1921.

The unseasonable warmth will come to an end in Adelaide today. A surface trough is expected to pass over the capital city later this afternoon, bringing a cool southerly change. Cooler temperatures will follow early next week but maximum temperatures are expected to reach the upper 20s again from Wednesday.
