Traveller notes on Sydney in March
Other months in Sydney
The Sydney forum's read on November: warm, spring-into-summer days that can spike into the low 30s°C with a fast afternoon storm, but the harbour itself is still too cool for most people to swim in comfortably — that's a December problem.
November is the pick: 24°C, water warm enough for the Bondi-to-Coogee swim, and the summer humidity hasn't arrived. Southerly busters roll through and drop 10 degrees in twenty minutes — the forecast never quite catches them.
