Why is Hornsby often cooler than the city?
Hornsby’s higher elevation (about 180 metres) and its position away from the coastal heat sink mean temperatures are typically 2–4°C lower than Sydney CBD, especially on clear nights. This also means more fog in winter.
Is the wind stronger in Hornsby than at the coast?
Generally no. The coast gets the full force of the sea breeze. Hornsby, being inland and on a ridge, experiences a moderated version, though afternoon north-easterlies can still be noticeable on exposed hills.
