Sydney’s climate

New South Wales, Australia · 33.87°S, 151.21°E · Australia/Sydney

Sydney has a humid subtropical climate with mild winters and warm summers. Seasons are reversed from the northern hemisphere: highs average about 27°C in January and 18°C in July, with lows of 20°C and 9°C. Frost is almost unknown near the coast.

Sea breezes keep the coast cooler than the western suburbs, where hot westerly winds can push summer days above 40°C.

Switch between daily, weekly, monthly and yearly views to compare a single date, a rolling week or month, or a full year. Dates are resolved in Sydney's own timezone (Australia/Sydney), not yours.
