Plan your Sunday around a mainly fine day: the live forecast above shows mostly sunny skies, a top temperature in that range, and light south-westerly breezes – ideal for being outdoors without needing heavy layers.
What’s driving Perth’s Sunday weather?
A ridge of high pressure off the coast is directing a stable airmass over Perth, keeping clouds thin and rain absent. The morning may start cool after a clear night, but by mid-afternoon the mercury rises to the forecast peak. Winds shift from light easterly to a gentle sea breeze by late morning, topping out near 20–25 km/h.
UV and sunset timing – what else matters?
With clear skies the UV index is likely to climb into the high range by late morning. Sun protection is recommended from about 9am until late afternoon. Sunset falls shortly after 6pm local time, so evening plans should have enough natural light for a post-dinner stroll.
Will it feel much hotter than the forecast maximum?
In direct sun the “feels-like” temperature may be 2–3°C above the air temperature due to the strong solar radiation and relative humidity near 40%. However, the sea breeze will provide noticeable relief by early afternoon.
What’s the best time to go to the beach on Sunday?
Mid-morning to around 3pm offers the warmest water and air, but the UV index is very high during those hours. Early morning (before 9am) or late afternoon (after 4pm) are safer options for extended sun exposure.
Could the forecast change significantly overnight?
Unlikely during a ridge pattern. The Bureau of Meteorology’s latest model runs show consistent guidance. Check the Perth Weather page for any updates before heading out.
