How often is the Perth weather forecast updated?

We refresh current conditions and the outlook regularly through the day, so the temperature, hourly strip and rain radar reflect the latest data. The seven-day outlook is recalculated as new model runs come in.

How accurate is the seven-day forecast for Perth?

The first three to four days are the most reliable. Accuracy tapers over the back half of the week, so treat the far end of the outlook as a guide to the trend rather than a firm promise. For plans in the next day or two, the hourly strip is the most dependable view.

What does "feels like" temperature mean?

The "feels like", or apparent, temperature blends the air temperature with humidity, wind and sunshine to estimate how the conditions actually feel on your skin. Wind and low humidity make it feel colder than the thermometer reads, while high humidity and strong sun make it feel warmer.

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.

What the UV index actually means

The UV index rates the strength of the sun's ultraviolet radiation on a simple scale. Below 3 is low and you can be outside safely without protection. From 3 to 7 is moderate to high, the point at which sunburn becomes likely within an hour, so a hat and sunscreen earn their keep. Above 8 is very high to extreme, and skin can burn in minutes around the middle of the day. The index peaks at solar noon, not at the hottest part of the afternoon, so the safest habit is to check the number rather than judge by the temperature.

Why the overnight low matters as much as the high

Daytime maximums get the headlines, but the overnight minimum shapes how the day actually feels. A cold night means a slow, crisp start and, on clear evenings, the chance of fog or frost before dawn. A mild night means the warmth carries over and the morning is comfortable from the outset. Clear skies let heat escape and push the low down; cloud cover traps it and keeps the night warmer. That is why two days with the same maximum can feel completely different depending on the night that came before.
