Plan your day in Gwelup around the live forecast above – it shows a mild autumn afternoon with light sea breezes. Morning cloud should clear by midday, making it a good window for outdoor errands or a walk around Lake Gwelup.
What will the weather feel like this week?
The week ahead stays mostly dry as a high-pressure system sits over the Bight. Days will hover near 24°C with afternoon easterly winds. Night-time lows drop to 12°C, so keep a jumper handy. Showers are unlikely until late in the seven-day outlook when a trough may brush the coast.
How does Gwelup’s location affect its forecast?
Gwelup sits about 13 kilometres north-west of the Perth CBD, close to the Indian Ocean. That coastal position moderates temperature extremes: summers are rarely scorching and winters stay above 10°C. Morning sea breezes often arrive by 10 am, dropping the temperature a few degrees and stirring up the surf at nearby beaches.
Is it often windy in Gwelup?
Yes, especially in the afternoon. The sea breeze – known locally as the Fremantle Doctor – kicks in around midday and can reach 25–30 km/h. It’s strongest from November to March. Morning walks or early bike rides are usually calmer.
When does the rainy season start?
Gwelup’s wettest months are June and July, with about 170 mm of rain each. Showers become more frequent from late April. Until then, expect dry and sunny days with the occasional evening drizzle from west-coast troughs.
What UV level should I expect today?
Autumn UV index in Gwelup ranges from moderate (3–5) in the morning to high (6–7) around 1 pm. If you’re outside between 10 am and 3 pm, wear SPF 30+ sunscreen. The sea breeze can make you think the sun is weaker – it isn’t.
