Adelaide, Australia

Adelaide sits in the Mediterranean basin in Australia, and the 2015–2024 weather record gives its sunshine a clear shape: the January peak reaches a 98/100 sun score, with daytime highs around 28°C — a solid base for a long-weekend city trip.

January is the heat peak, averaging 28°C highs; July is the cool end, when nights dip to around 8°C. The wet–dry contrast is pronounced: 44% rain-day odds in July against 9% in February. The genuinely warm window — average highs of 24°C or better — covers January–March and December.

The seasonal arc is clear in the data: summer averages 15°C against winter's 27°C, while rain-day odds move from 12% in winter and 23% in spring to 43% in summer and 30% through autumn. Winter wins on the numbers and summer loses them; everything in between is a trade-off between warmth and crowds. If your dates are flexible, January buys you 28°C warmth at the quiet end of the season.
