Perth weather, explained

How to read the Perth forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when it is warm enough to walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Perth.

Perth weather and the coast

Perth's weather is shaped by its position on a flat coastal plain between the Indian Ocean and the Darling Scarp to the east. Summer mornings often start with warm, dry easterlies rolling down off the escarpment, pushing temperatures up quickly. The relief almost always comes from the west: the Fremantle Doctor, a strong south-westerly sea breeze off the Indian Ocean, arrives most summer afternoons and can drop the temperature ten degrees or more in under an hour. In winter, cold fronts sweep in from the Southern Ocean bringing the rain bands that fill the dams, with mild days between them — a hot-summer Mediterranean rhythm of dry summers and wet, mild winters.

What the UV index means in Perth

Perth sits at 32 degrees south, which puts it in a UV band that surprises many visitors. On clear summer days the UV index regularly reaches 11 or above, meaning skin can burn in under ten minutes around midday. The index peaks at solar noon, not at the hottest part of the afternoon, so checking the number rather than judging by the temperature is the most reliable habit. Below 3 is low and you can be outside without extra protection. From 3 to 7 means sunscreen earns its keep. Above 8 means a hat, sunscreen and shade are all genuinely useful, not optional.
