What drives Perth’s hourly changes today?

Perth’s hourly temperatures follow a predictable curve: morning lows near 16°C, a rapid climb through the mid-20s by 11am, and the peak around 3pm. The afternoon seabreeze, typically arriving from the southwest between 2pm and 4pm, will shave 2–3°C off the maximum and bring a noticeable drop in humidity. Winds remain light overnight, settling to a calm 5–10 km/h. This pattern is typical for February, when the city averages 31°C daily highs and 17°C overnight lows.

How does the 14-day outlook shape hourly expectations?

The Perth Weather page shows the 14-day trend holding steady, with no rain events in the next week. This means each day’s hourly profile will look similar: clear mornings, hot middays, and a reliable seabreeze. For weather perth 14 days, expect daily highs between 26°C and 33°C, with the coolest mornings around 15°C. The Australia weather hub confirms this as a stable high-pressure ridge sitting over the southwest.
