What’s driving Pennant Hills’ weather today?
Pennant Hills sits on the ridgeline of the Hornsby Plateau, about 100 metres above sea level, which means it often catches a slightly cooler breeze than the inner city. The live forecast above accounts for that elevation. If the wind swings from the west, temperatures can drop rapidly after sunset – a pattern shared by nearby Kellyville and West Pennant Hills. For broader Sydney weather patterns, coastal influences can either amplify or soften these inland effects.
