Weather Overview for Perth
The annual average rainfall is about 850mm, and some rain falls on about 110
days a year on average. Rainfall is normally heavy and brief, although cyclone
systems that occur north of
Humidity is low, ranging from about 40% in winter to about 60% in summer.
Summer: December to February
Summer runs from December to February because
Summer days see average highs of 32°C and lows of 17°C. Temperatures can however get much higher – often soaring into the 40s for a few days each summer. Last year saw 9 days recording a temperature over 40°C, which was far higher than the average of 3 days. The highest temperature ever recorded was a sweltering 46°C. At the other end of the scale, it is unusual to see summer temperatures drop below the mid-teens.
There is relief, however, on the hottest summer days from the famous ‘Fremantle Doctor’: the strong wind that blows in off the ocean. This wind is said to be the most consistent in the world, blowing daily between noon and 3pm. It’s a southwest wind that is caused by the temperature difference between the sea and the land and can penetrate as far as 100km inland.
The Fremantle Doctor is famous to cricket lovers as it often plays an important role in matches at the Waca. It can be a hindrance to bowl into, but those who get it right can utilise the breeze to help swing the ball. The wind is also a welcome arrival for the fielders!
Winter: June to August
You never get snow but winter is when most of the rain falls. June, July and August account for over half of the yearly rainfall. June and July are the wettest, both seeing about 160mm of rain on average. August sees a little less rain, but still over 100mm.
The sea remains warm, not falling below 19°C. Sunshine levels hit their bottom in June and July at 5 hours per day which is still pretty sunny.
