The live forecast above gives Perth’s hourly conditions today, showing temperature, wind and rain-chance trends from dawn through the evening, with the warmest part of the day expected in the early to mid afternoon.
What does the hourly forecast tell me about today?
The detailed timeline helps you plan outdoor activities by highlighting when conditions shift. Key points to watch:
- Morning: usually cooler and calmer, with lighter winds and lower temperatures before 9 am – ideal for a walk or run.
- Midday to early afternoon: the daily peak in temperature, often accompanied by a strengthening sea breeze. Check the live forecast above for the exact timing.
- Late afternoon and evening: temperatures drop steadily, but the south-westerly wind may persist. Rain chances, if any, are typically higher near dusk.
For a broader view, see the Perth weather page or the 10-day forecast to compare hourly changes over the coming week.
How reliable is the hourly breakdown?
Perth’s coastal location means sea breezes and cloud cover can shift quickly, so the forecast is most accurate for the next 12 to 24 hours. Factors that affect reliability:
- Wind direction: a change from easterly to south-westerly is common and well predicted by models, but timing can vary.
- Thunderstorm potential: summer storms are localised and may not appear in hourly tables until a few hours ahead.
- Check the Bureau of Meteorology for updates and the Weatherzone radar for real-time changes.
When is the best time to visit Perth beaches?
The calmest conditions are usually before 10 am, when winds are light and the water is flat. After noon the sea breeze picks up, making it popular for windsurfing and kitesurfing but less relaxing for swimming.
How does the afternoon sea breeze affect the hourly temperature?
The Fremantle doctor arrives around midday, dropping temperatures by 2–5°C within an hour. The live forecast above shows this drop, often followed by a steady plateau into the evening.
