What defines Werrington Downs’ weather pattern?
Werrington Downs sits on the Cumberland Plain, about 50 kilometres west of the Sydney CBD. This location means it receives less coastal moderation than eastern suburbs. Summer days often reach the low 30s Celsius, while winter minimums can drop to single digits. The area’s average annual rainfall is around 700 millimetres, with most falls occurring in late summer and autumn from thunderstorms.

On clear winter mornings, fog can linger until 9am, especially after rain. Check the Bureau of Meteorology radar for approaching cells.
Does Werrington Downs get thunderstorms often?
Yes, western Sydney has a higher thunderstorm frequency than the coast. Werrington Downs averages about 20–25 storm days per year, mostly in spring and summer. Storms can bring localised flash flooding and damaging wind gusts.
What is the typical summer humidity?
Humidity in Werrington Downs is usually lower than near the coast, ranging 40–60% on summer afternoons. Prefrontal north-westerly winds can drop humidity below 20%, raising fire danger, while moist easterly changes push it above 70%.
