Sydney in October

Warm spring sun, and the sea slowly eases. The regional bushfire danger period begins in spring, with the start date shifting a little each year. Jacarandas start to bloom with purple flowers in the second half of the month.

Highs of 24°C and lows of 15°C: short sleeves by day, with mild nights. 9 rain days in a typical October: noticeable, but most days stayed dry. A visitor in 2013 met 2 rain days; one in 2022 met 20. The average of 9 hid that gap.

Highs passed 30°C on 4 days on average. October 2025 averaged 26.5°C by day, 2.9°C above the 20-year mean.
