Adelaide just had its warmest June night in 24 years.

The temperature at Adelaide's West Terrace weather station only dropped to 16.3 degrees on Friday morning. This was the city's highest June minimum temperature since 16.7 degrees at the Kent Town station back in 1995.

Northerly winds gusting above 30 km/h for most of Thursday night kept the mercury up in the mid-to-high teens. Windy conditions at night mixes the low levels of the atmosphere, which prevents cool air from pooling near the surface as the ground loses heat through radiative cooling.

Calm nights with no clouds are usually the ones that cause the lowest temperatures during winter.

Adelaide's highest minimum temperature on record during June was 17.3 degrees in 1919.
