Byron Bay, Australia

Byron Bay sits under a tropical sky in Australia, and the 2015–2024 weather record gives its sunshine a clear shape: the August peak reaches a 91/100 sun score, with daytime highs around 21°C — a solid base for a sand-and-sea holiday.

Across a typical year, afternoon temperatures swing between 19°C (June) and 27°C (January). The wet–dry contrast is pronounced: 67% rain-day odds in March against 25% in July. Beach-warm afternoons (24°C and up) hold through January–March and November–December.

Averaged by season, sun scores land at 84 for spring, 85 for summer, 90 for autumn and 88 for winter — with typical afternoons of 24°, 20°, 24° and 27°C respectively. Autumn wins on the numbers and spring loses them; everything in between is a trade-off between warmth and crowds. If your dates are flexible, January buys you 27°C warmth at the quiet end of the season.
