What’s driving Forrestdale’s weather today?
Forrestdale sits in Perth’s south‑eastern suburbs, under the influence of a large high‑pressure system centred over the southern Indian Ocean. This ridge keeps skies clear and winds light, allowing strong daytime heating. No rain is expected in the next 48 hours.
How does this compare to the seasonal norm?
January and February are Forrestdale’s hottest months, with average maxima around 32°C. Today’s forecast is slightly above that, which is not unusual during a heatwave spell. Overnight lows will be mild, around 18–20°C, offering some relief.
Will it cool down overnight in Forrestdale?
Yes. Temperatures drop to around 18–20°C after sunset, thanks to clear skies and a light land breeze. That’s still warm enough for a comfortable evening outdoors.
Is there any chance of a thunderstorm?
No. The high‑pressure system keeps the air stable and dry. No clouds of thunderstorm potential are forecast for the next three days in the Forrestdale area.
What’s the UV level today?
UV Index is forecast to reach 11–12 in the early afternoon (Extreme). Slip on protective clothing, apply SPF50+ sunscreen and seek shade between 10am and 4pm.
