Pennant Hills weather today is mild with partly cloudy skies, as shown in the live forecast above. Located in Sydney’s northern suburbs, the area experiences warm summers and cool winters, typical of the coastal lowlands of the Central Coast. Light winds from the east keep humidity moderate through the afternoon.
What is the summer and winter pattern like?
Summers in Pennant Hills are warm but not extreme, with heat moderated by sea breezes. Winters are cool and fairly dry, with overnight temperatures often dropping into single digits. Rain falls year-round, with a slight winter maximum from easterly troughs.
How does the local geography affect the weather?
The suburb sits on the undulating shale hills of the Hornsby Plateau, roughly 100 metres above sea level. This elevation gives slightly cooler nights than the Sydney CBD, and morning fog can linger in valleys. The terrain also influences local wind patterns, especially during thunderstorm outbreaks.
How accurate are hourly forecasts for Pennant Hills?
The Bureau of Meteorology (BOM) provides hourly updates based on high‑resolution models. For routine days, accuracy is reliable within a few hours, but thunderstorms can shift quickly – check the live forecast above for the latest.
Does Pennant Hills get severe weather?
Strong east coast lows can bring heavy rain and damaging winds, especially in autumn and winter. Hail and flash flooding occur occasionally during summer thunderstorms. Monitor severe‑weather warnings from BOM for Sydney weather alerts.
Is the weather different in nearby Kellyville or West Pennant Hills?
Kellyville and West Pennant Hills lie slightly further inland and at similar elevation, so temperatures and rain are nearly identical. The main difference is wind exposure – western suburbs can be a degree or two warmer in afternoon north‑westerlies.
