Sydney Weather Today — Current Conditions and 7-Day Sydney Forecast

Sydney Weather Today

Sydney's weather is shaped by its coastal position on the Tasman Sea and the influence of the Great Dividing Range to the west. The city experiences a temperate climate with warm summers, mild winters and moderate rainfall distributed fairly evenly across the year. The Bureau of Meteorology (BOM) classifies Sydney as having a humid subtropical climate, though locals know that conditions can change rapidly — particularly when afternoon sea breezes battle westerly hot air masses in summer.

Sydney Climate — What to Expect Each Season

• Summer (December to February) — Hot and humid with temperatures regularly reaching the high 20s to mid-30s. Thunderstorms are common in the afternoons, particularly in western Sydney. January averages 25.8°C. Heatwaves can push temperatures above 40°C in western suburbs while coastal areas remain cooler.
• Autumn (March to May) — Warm and settled, widely regarded as Sydney's finest season. Temperatures ease to the comfortable 20s with lower humidity and reliable sunshine.
• Winter (June to August) — Mild by international standards. Average minimum temperatures in Sydney rarely drop below 8°C in coastal areas. Frost is virtually unknown in the city, though Blue Mountains suburbs experience cold conditions. July averages 12.1°C minimum, 17.0°C maximum.
• Spring (September to November) — Variable. September and October can bring gusty winds and unpredictable storms. November warms quickly. Spring is peak bushfire weather risk season for the greater Sydney region.

Sydney Rainfall

Sydney receives approximately 1,213mm of rainfall per year, spread fairly evenly with a slight autumn peak. March is typically the wettest month. Sydney's rainfall can vary dramatically between the CBD and western suburbs, with areas like Penrith running 15-20% drier than Observatory Hill.

Sydney Suburb Weather — Does It Vary?

Sydney's weather varies significantly across its suburbs. Western suburbs (Penrith, Parramatta) are typically 4-8°C hotter than the CBD on hot days due to the urban heat island effect and distance from sea breezes. Coastal suburbs (Bondi, Manly, Cronulla) benefit from afternoon sea breezes that moderate temperatures. Southern Highlands suburbs experience lower temperatures year-round than city areas.
