For Coolbellup, check the live forecast above for today’s conditions; the suburb typically enjoys mild winters and warm summers, with the best travelling weather from November to March when you can expect clear skies and temperatures in the mid-20s Celsius.
When is the best time to visit Coolbellup for fine weather?
The most reliable period for outdoor plans is between November and March, when daytime highs hover around 24–30°C and rainfall is at its lowest. This coincides with the school summer holidays, so book accommodation well ahead if you are planning a trip around Christmas or the Australia Day long weekend. Autumn (March to May) offers a pleasant alternative with cooler evenings and fewer crowds.
What should I pack for Coolbellup weather?
In summer, pack light clothing, a hat, sunscreen and a reusable water bottle as the sun is strong. Evenings can cool down, so a light jacket is handy. For winter (June to August), bring a warm coat and a rain jacket; daytime temperatures range from 8–18°C and showers are common. Sturdy walking shoes are useful for exploring nearby parks and the coast.
Does Coolbellup get much wind?
Yes, Coolbellup can experience a sea breeze in the afternoon, especially from November to March. Wind speeds typically range from 15–30 km/h, so secure loose items if you are camping or picnicking near the coast.

What is the best time to avoid rain in Coolbellup?
January and February are the driest months, with rainfall averaging under 20mm each. If you want to dodge the wet, plan a visit during those months rather than in winter when June and July are the wettest.
