Sydney is a great destination to visit year round due to its moderate climate. In summer temperatures are warm but not too humid while winter temperatures are mild and days are often noted for their blue, sunny clear skies. This makes it a perfect city to enjoy alfresco dining, frolicking on beaches, cruising on the harbour and scenic walks in the many parks and gardens.
Temperatures and Rainfall
Historical records show that Sydney tends to have its heaviest rainfall in March but summer months (Jan- Mar) also receive significant rainfall at 130mm per month.
Average annual temperatures range between 13 to 22 degrees are suitable for outdoors activities year round. The city is prone to sudden thunderstorms in the warmer months but these tend to arrive in the late afternoon after warm and humid days. Occasionally the city experiences heat waves of 30 degrees and over, however, the warmer than average temperatures only lasts a few days before cooling down again to average summer temperatures of 26 degrees.
The Australian summer runs from December to February with average temperatures ranging from 17 – 26 degrees and humidity at 65%. Summer is the perfect time to soak up the sun and enjoy the many beaches, outdoor pools and alfresco dining on offer. Water temperatures are comfortable and perfect for an ocean swim or surf at 24 degrees.
The warm and humid temperatures produce thunderstorms and showers that normally build throughout the day and arrive in the afternoon. It is common to have a perfect sunny day with blue skies and then have storms clouds roll in very quickly before dissipating again.
Autumn begins from March to May and while warm summer temperatures can still be experienced the humidity drops making the temperatures far more comfortable and bearable. The average temperatures range from 14- 22 degrees.
Autumn is a great time to visit Sydney to enjoy sunny, warm weather. The water temperatures are still comfortable to swim in and May marks the beginning of the Humpback Whale migration that runs through to August. The days are still warm enough for shorts and t shirt but light layers are needed in the evenings when the temperature drops.
Autumn is considered off peak so you will find that hotel and flight prices will have dropped slightly from summer/peak prices which means more money in your pocket to spend on experiences while in Sydney.
Winter in Australia runs from June to August with temperatures ranging from 8- 17 degrees. The cooler temperatures are generally only felt in the evenings with average daytime temperatures around 13 degrees.
Historically, June does receive the most rainfall at 132mm for the month. The Australian winter is very mild in Sydney and many visitors comment that our winters are equivalent to Summer in the Northern Hemisphere. The city is prone to fog in the early morning which can disrupt flights and harbour cruises but disappears pretty quickly once the sun comes out.
Vivid Festival is a big hit in winter. The annual festival of light, music and ideas turns public building into art installations. The festival is also accompanied by outdoor sculptures and exhibits, music and theatre programmes and runs over 3 weeks.
Spring runs from September to November and is arguably the best time to visit Sydney because the city has warm temperatures without the summer humidity. Sydney’s parks and gardens are best viewed at this time with colourful flowers in bloom.
Spring is when Sydneysiders come out of hibernation and head outdoors to enjoy the warmer temperatures. There are also a number of festivals including the famous Sculptures by the Sea that showcases visual art to the public for free at various beaches around Sydney.
Average temperatures in spring range between 11 – 23 degrees. By November the temperatures and humidity are building for summer. Occasional thunderstorms can be experienced in late spring but these normally only last a short time before clear skies emerge again.
