In summer the average minimum is around 15.1 to 16.8 °C and the average maximum is around 26.8 to 28.5 °C,Weather In Adelaide [https://www.australia.com/en/facts-and-planning/weather-in-australia/adelaide-weather.html "Weather In Adelaide"], Tourism Australia Retrieved 28 August 2023. but there is considerable variation and Adelaide can usually expect several days a year where temperatures reach the mid/high 30s to low 40s. On a few rare occasions the temperature has reached the mid 40s. These high temperatures usually occur when hot northerly winds blow hot air down south from central Australia, causing the temperature to spike.{{Cite news |date=2025-02-11 |title=Hot weather warning for SA as high temperature records expected to be broken |url=https://www.abc.net.au/news/2025-02-11/hot-weather-fire-warning-temperatures-soar-in-south-australia/104923622 |access-date=2025-02-19 |work=ABC News |language=en-AU}} However, the weather, like Melbourne, Victoria, can be rather changeable as it is not uncommon to have days where the temperature peaks in the low 20s when there is a cool southerly wind blowing cooler air from the Southern Ocean.{{Citation needed|date=February 2025}} Occasionally, the high may remain below 20 degrees, even in the peak of summer.

Rainfall is unreliable, light and infrequent throughout summer. The average in January and February is around 20mm, but completely rainless months are by no means uncommon.{{Cite web |date=2024-02-27 |title=Adelaide staring at a rainless February |url=https://www.weatherzone.com.au/news/adelaide-staring-at-a-rainless-february/1820597 |access-date=2025-02-19 |website=www.weatherzone.com.au |language=en}}

In autumn, the weather is generally mild. Average minimum temperatures vary between 10.4 and 15.2 °C, while maximums vary between 18.6 and 26 °C.Weather In Adelaide [https://www.australia.com/en/facts-and-planning/weather-in-australia/adelaide-weather.html "Weather In Adelaide"], Tourism Australia Retrieved 28 August 2023.

There is very little rainfall until late Autumn.{{fact|date=February 2025}}

In winter the average maximum is around 14 to 16 °C and the average minimum around 7 to 9 °C,Weather In Adelaide [https://www.australia.com/en/facts-and-planning/weather-in-australia/adelaide-weather.html "Weather In Adelaide"], Tourism Australia Retrieved 28 August 2023. although temperatures again can fluctuate. Note though that the temperature rarely drops below freezing or rises above 19 °C. Frosts are common in the valleys of the Adelaide Hills, but rare elsewhere. Winter in Adelaide also sees quite a significant wind chill, which makes the apparent temperature seem colder than it actually is.

Winter has fairly reliable rainfall with June being the wettest month of the year, averaging around 80 mm. The city's dry summers are attributed to the Australian High on the Great Australian Bight.

Like Autumn, spring weather is mild. Average maximum temperatures vary between 18.4 and 24.4 °C.Weather In Adelaide [https://www.australia.com/en/facts-and-planning/weather-in-australia/adelaide-weather.html "Weather In Adelaide"], Tourism Australia Retrieved 28 August 2023. Despite the warmer days, with little cloud cover, overnight temperatures can drop quickly, minimums varying between 9.2 and 13.1 °C.Weather In Adelaide [https://www.australia.com/en/facts-and-planning/weather-in-australia/adelaide-weather.html "Weather In Adelaide"], Tourism Australia Retrieved 28 August 2023.

Rainfall tapers off quickly from winter into spring.

This heatwave is even more exceptional because it didn't occur in summer.{{citation needed|date=November 2021}}

During January and February 2009 Adelaide was affected by the early 2009 southeastern Australia heat wave. The heatwave broke numerous records and affected all of south-eastern Australia, including Melbourne, where some outdoor games were cancelled during the 2009 Australian Open.

The heatwave commenced in Adelaide on 26 January 2009 (Australia Day), with a temperature of {{convert|36.6|°C|0|abbr=on}}. From 27 January the temperature soared above {{convert|40|°C|0|abbr=on|}} degrees for 6 consecutive days, until 2 February where the temperature dropped to {{convert|38.8|°C|0|abbr=on|}}. This is the longest straight run of {{convert|40|°C|0|abbr=on|}} temperatures in Adelaide. On 28 January, the third day into the heatwave, the temperature reached {{convert|45.7|°C|0|abbr=on}}, making it the third-hottest day on record in Adelaide. On that same night, the temperature only dipped to {{convert|33.9|°C|0|abbr=on|}}, making it the highest minimum temperature on record in South Australia (since surpassed). The maximum temperatures stayed higher than {{convert|30|°C|0|abbr=on}} for another six days, including two more 40-degree-plus days (6 and 7 February) until dropping back to {{convert|24.8|°C|0|abbr=on}} on 8 February 2009.

In November 2009 Adelaide was affected by the late 2009 southeastern Australia heatwave which occurred in the states of South Australia, Victoria and New South Wales. Daily maximum temperatures during the heat wave were roughly {{convert|10|C-change|F-change}} above average in many locations. Capital cities Adelaide and Melbourne recorded temperatures over {{convert|40|°C|°F}} and {{convert|35|°C|°F}}, respectively, which are unusual for November. Above-average temperatures in the region began in late October and persisted until mid-November 2009.

Temperature records for November in Adelaide set during the heatwave:

• 10 consecutive days over {{convert|30|°C|°F}}.
• 8 consecutive days over {{convert|35|°C|°F}} – new record set on 13 November, breaking the previous record of 4 consecutive days, which was set in 1894.{{Cite news | title = Adelaide sweats in landmark heatwave | publisher = ABC News Online | date = 12 November 2009 | url = http://www.abc.net.au/news/stories/2009/11/12/2740805.htm | archive-url = https://web.archive.org/web/20091113054358/http://www.abc.net.au/news/stories/2009/11/12/2740805.htm | url-status = dead | archive-date = 13 November 2009 | access-date = 12 November 2009}}
