Sydney Weather & Climate

Sydney enjoys a temperate climate with warm weather in summer and mild winters. The city itself averages 340 sunny days each year. The Western Suburbs of Sydney are generally warmer during the day and cooler at night due to their position further away from the coast.

From December to February, summer offers some of the best weather suited to the beach and outdoor lifestyle of Sydney. Temperatures average about 26 degrees Celsius but can sometimes get hotter, up 40 degrees Celsius. The humid conditions of a Sydney summer is buffered by dry winds and cold fronts from the south. These sometimes cause storms which pass quickly but help to cool temperatures down in the evening.

Autumn falls from March to May and still enjoys warm weather but with more mild nights. Days are still generally good for outdoor activities like going to the beach but the change in weather means temperatures drop and visitors may wish to spend their time visiting attractions and riding the ferry on the harbour without the crowds summer brings.

June to August sees winter bring cooler weather however temperatures don't drop too dramatically. Ranging from 10 degrees Celsius to an average maximum of 17 degrees Celsius, the winter weather is still quite pleasant although can sometimes attraction low pressure systems offshore bringing with it a few rainy weeks.

Spring is from September to November and offers lovely weather for exploring the city or the outdoors. The weather is warm and sunny without being too hot and the beaches are patrolled from October. Enjoy some of Sydney's wonderful outdoor attractions and visit the beach before the crowds return in November.

Known as the El Nino - Southern Oscillation (ENSO), this global ocean-atmosphere phenomenon occurs when it meets with a La Nina weather pattern and, combined with East Coast low pressure systems, causes hail storms and flash flooding in Sydney. Despite causing widespread damage, these major events only cycle through every three to eight years.

The below rainfall table demonstrates the well spread nature of most of Sydney's annual rainfall. While the easterly winds dominate the beginning of the year causing higher rainfall, by the middle of the year the average continues to drop.
