Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Coast Monitor Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
Check the live forecast above before heading out. Blacktown’s weather is shaped by its inland western Sydney location, meaning summer days often run hotter than the coast and winter mornings can be crisp.
What is the typical weather pattern for Blacktown today?
Blacktown sits on the Cumberland Plain, away from coastal sea breezes. This means afternoon temperatures in the live forecast above are usually a few degrees warmer than central Sydney. East to north-east winds develop in the afternoon, while mornings can be calm. Showers, when they occur, tend to arrive from the east.
How reliable are the 7-day and 14-day forecasts for Blacktown?
The Bureau of Meteorology’s 7-day outlook for Blacktown is generally reliable for temperature trends and broad rain chances. Forecasts beyond 7 days (weather in blacktown 10 days, weather blacktown 14 days, blacktown weather 30 days) carry more uncertainty. For day-to-day planning, the bom weather blacktown 7-day page is your best bet. For hour-by-hour detail, check weather in blacktown tomorrow and blacktown weather hourly updates.
Does Blacktown get hotter than the Sydney CBD?
Yes. Because Blacktown is inland, it misses the cooling sea breeze. On a 35°C day in the city, Blacktown can easily reach 38–40°C. Always check the live forecast above for actual readings.
When is the best time to check weather blacktown today time and date?
The most accurate snapshot is the 6am and 9am BOM updates. These capture the morning trend and any approaching troughs. For real-time changes, look at the hourly table on the bureau’s site.
Is thunderstorm risk higher in Blacktown than near the coast?
Yes. The inland heat and westerly flow often trigger afternoon storms in spring and summer. The Severe Weather Warning page is worth checking if storms are forecast.
