Terrey Hills is enjoying a mild, partly cloudy autumn day according to the live forecast above, typical for this elevated pocket of northern Sydney.
What’s driving today’s conditions over the Hills?
A high-pressure ridge sitting off the New South Wales coast is keeping most shower activity at bay, though a light easterly flow is dragging some moisture inland from Broken Bay. Temperatures should peak near the forecast high, with an afternoon sea breeze arriving earlier than usual.
How does the local terrain shape the weather?
Sitting about 200 metres above sea level, Terrey Hills is often a few degrees cooler than the Sydney CBD. The area’s native bushland and proximity to Ku-ring-gai Chase National Park can trap overnight fog in winter, while summer afternoons frequently trigger storm cells that drift south over the northern suburbs.
How reliable is the Terrey Hills weather radar?
The BOM’s Terrey Hills radar (code 512) covers the Sydney basin and northern suburbs well. Like all radars, it can overestimate rainfall in heavy drizzle and miss shallow showers, so always cross-check with local observations.
Does Terrey Hills get more rain than central Sydney?
Yes, generally. Its higher elevation and position on the edge of the coastal escarpment mean it intercepts more orographic rain and afternoon storms, often recording 200–300 mm more annually than Observatory Hill.
Where can I find the hourly forecast for Terrey Hills?
