Check the live forecast above for today’s exact conditions, but expect Perth’s typical pattern: a warm morning giving way to a sea breeze that drops the temperature by mid-afternoon. This coastal shift is driven by the Indian Ocean’s cooling influence.
What’s driving today’s weather in Perth?
Today’s conditions are shaped by the position of the subtropical ridge and any weak troughs moving across the southwest. In summer, a easterly morning winds often shift to a southerly sea breeze. In winter, cold fronts from the Southern Ocean bring rain and cooler temperatures. The live forecast above shows which system is currently influencing the city.
What does the UV and wind mean for your day?
Perth regularly records high UV levels, especially from September to April. The live forecast above includes the UV index; when it reaches 3 or above, wear sun protection. Wind speeds typically peak in the late afternoon as the sea breeze strengthens, affecting outdoor plans along the coast.
How does today compare to the forecast for the week?

What’s the best time to go to the beach today?
Mornings are usually calmer, with lighter winds and lower UV. The sea breeze builds from late morning and strengthens by early afternoon, so swimmers often prefer 8am–11am. Always check the live forecast above for wind direction and swell conditions.
How accurate is the weather in perth 10 days forecast?
The 10-day outlook is useful for general trends (e.g. a cooler change or dry spell), but day-to-day accuracy drops after day 7. For today’s decisions, rely on the live forecast above and the weather perth 14 days bom model as a guide for pattern rather than exact temperatures.
