Sydney Weather

Sydney sightseeing

Sydney weather is temperate, with warm summers and mild winters. Rainfall is pretty evenly spread throughout the year but Summer tends to be slighter wetter. The average annual rainfall is 1217 mm with rain actually falling on 138 days a year. Sydney is famous for its clear blue sky days and it experiences more clear days in winter than any other capital city. The warmest time is between October and March and the autumn/winter period is April - September. During the spring/summer period temperatures will be in the range 15 – 26C and in the autumn/winter period in the range 10 - 22C.

Sydney has a temperate climate. Rain is not predictable but most likely in the period February to July, however in recent years Sydney has been very dry as shown by the number of bush fires in the summer months.

Hot summer days often end with a "Southerly buster", a cold front sweeping up from the south which cools the temperature.

Snow is extremely rare - the last time reported in the CBD area was in 1836. Hailstorms are regular - and often mistakenly reported as snow - and in 2008 a major storm saw many news outlets reporting a snow storm. The city is not affected by cyclones but can experience some heavy storms with flash flooding, the worst being on August 6, 1986 when 327.6mm of rain was dumped on the city in 24 hours.

Sydney weather is generally determined by the ocean, preventing some of the more extreme temperatures experienced further inland. Sydney experienced its hottest day on January 14, 1939 when the thermometer reached 45.3C. The warmest month is January with an average temperature of 25.8C, although the temperature can climb into the low 30s centigrade. Afternoon sea breezes are normal for Sydney - and on a hot day very welcome - nut they rarely reach the western suburbs where temperatures can be up to five degrees higher.

Autumn can be very pleasant in Sydney with slightly milder temperatures, down to the low 20s centigrade, with humidity disappearing to make nights more bearable. Winter (between June and August) is mild, with some rainfall, the occasional storm, and average temperatures in July of 16-18C. Temperatures at night will rarely drop below 5C in coastal areas but western and south-western suburbs will experience a ground frost.

Springtime in Sydney brings strong westerly winds, which can last well into October, cooling the city down, before Summer arrives with its long hot days and strong sunshine. Sydney has a great climate - just be aware of the humidity in Summer and for visitors, the strength of the sun.
