Tallawong’s weather today, based on the live forecast above, is typical for Sydney’s north-west: warm with a chance of a late shower. The main thing to plan for is the afternoon temperature and any gusty change.
What is the typical weather pattern for Tallawong?
Tallawong sits in Sydney’s Hawkesbury region, so summers are hot and humid, often with afternoon thunderstorms. Winters are mild and dry, with cool mornings and clear skies. The area gets more extreme heat than coastal Sydney, especially in January and February.
How does the local geography affect Tallawong’s weather?
The nearby Blue Mountains block some westerly systems, but they also trap heat in the basin. This makes Tallawong a few degrees warmer than the city centre on summer afternoons. The lack of sea breeze means overnight temperatures can drop quickly in winter.
Does Tallawong get severe storms?
Yes. The north-west suburbs are a hotspot for summer thunderstorms, often with heavy rain, hail and damaging winds. Check the severe weather warning page if a storm is forecast.
Is Tallawong hotter than Sydney CBD?
Usually yes on summer afternoons. Without the coastal sea breeze, temperatures in Tallawong can be 3–5°C higher than at Observatory Hill. Overnight lows are similar or slightly cooler.
When is the best time to visit Tallawong?
Autumn (March to May) and spring (September to November) offer the most comfortable weather. Days are warm but not extreme, and rainfall is lower than in summer.
