Australia Sydney Weather in April — Climate Guide
April in Sydney is Very Good
April is Very Good for Sydney.
April is the proper autumn month — 22°C daytime, 15°C nights, sea temperature 20°C (borderline swim-comfort). Hotel rates 30% below peak. Crowds thin out. The shoulder-season sweet spot for travelers who don't need beach weather.
ANZAC Day (April 25) is Australia's most-solemn national day — dawn service at the Cenotaph in Martin Place + parades through CBD. Public transport free that day. The Two-Up gambling tradition at pubs is the canonical ANZAC Day afternoon.
