Allambie Heights, on the northern beaches of Sydney, is looking at a mild to warm day with a light sea breeze, though the live forecast above gives the specific conditions right now. Autumn is easing in, so afternoons tend to be pleasant with a chance of a late shower moving in from the coast.
What is the typical weather pattern for Allambie Heights?
Allambie Heights sits about 10 kilometres inland from the coast, so it often catches a slightly cooler morning than the beachfront suburbs, but warms up by midday. The sea breeze can arrive by early afternoon, keeping temperatures moderate compared with western parts of Sydney. Rainfall tends to be spread through the year, with autumn and early winter seeing occasional east-coast lows that bring soaking rain.
How does Allambie Heights compare with other Sydney suburbs?
Because it’s at a slightly higher elevation (around 100 metres), Allambie Heights can be a degree or two cooler than lower-lying areas like Frenchs Forest or Brookvale, especially on clear nights. The proximity to the ocean means humidity is often higher than inland Sydney, but the breeze usually keeps it comfortable. For a broader picture of Sydney weather, check the city forecast.
What is the hottest month in Allambie Heights?
January is typically the warmest, with average maximums around 26–28°C. However, occasional heatwaves can push temps above 40°C, especially when north-westerly winds blow before a sea breeze arrives.
Does Allambie Heights get fog?
Yes, especially in autumn and winter after clear, calm nights. The elevated terrain can trap shallow fog in the valleys, but it usually clears by mid-morning. This fog is more common than at coastal points like Dee Why.
Where can I find real-time observations for Allambie Heights?
The Bureau of Meteorology’s nearest AWS is at Terrey Hills, about 5 kilometres north-west. You can also check AccuWeather Allambie Heights for hourly forecasts, but the BOM remains the official source for warnings.
