What March is like in Sydney
March marks the transition into autumn, though it often feels like an extension of summer. Temperatures remain warm, with sea temperatures still around 22-23°C. East coast lows are most frequent during March and April, capable of dumping 200mm or more in 24 hours and generating dangerous surf. The humidity starts to ease toward month's end, and the first truly comfortable evenings arrive. March is statistically one of Sydney's rainiest months.
