Sydney enjoys a temperate oceanic climate with warm summers, mild winters, and sunshine distributed generously throughout the year.
Rainfall occurs year-round but peaks during the first half of the year, making a lightweight waterproof jacket a wise investment from February through June.
Summer temperatures regularly reach 26°C to 30°C with occasional heatwaves pushing past 40°C, while winter rarely dips below 8°C at night.
Coastal humidity can make summer feel sticky and oppressive, while the afternoon nor'easter sea breeze provides merciful relief to those near the harbour.
The city's fondness for outdoor dining and harbour-side activities means you'll want clothes that transition seamlessly from air-conditioned interiors to sunny terraces.
