Occasionally, strong thunderstorms develop in spring and summer, bringing heavy rain, hail or gusty winds. Check severe weather warnings during storm season (October–March) for updates.

The suburb itself is in a built-up area with low fire risk, but nearby bushland can be dangerous on hot, windy days. Stay alert to fire danger ratings and warnings from November to March.
