Hornsby’s weather is shaped by its inland-hills location northwest of Sydney, giving it slightly cooler mornings and warmer afternoons than the coast. The live forecast above shows today’s conditions; check it for the most accurate reading of what’s happening now.
What makes Hornsby’s climate different from the coast?
Because Hornsby sits about 180 metres above sea level and is sheltered from the immediate ocean influence by the ridge to the east, it records milder summer maximums and more pronounced overnight cooling than the city centre. Winter mornings often drop below 5 °C, producing frost in nearby valleys. The area receives around 1,200 mm of rain annually, with autumn and early winter the wettest periods due to east‑coast lows.
