Sefton is seeing conditions in line with the live forecast above — typical for this time of year in Sydney’s inner-south-west. The suburb, tucked between the Georges River and Bankstown, is currently under the influence of a coastal trough, bringing moderate south-easterlies and a chance of passing showers into the afternoon.

What is driving Sefton’s weather today?

A trough lingering over the Illawarra and Sydney basin is drawing moisture inland, keeping skies mostly cloudy over Sefton. The breeze off Botany Bay and the Cooks River corridor is moderating temperatures. If you need to plan outdoor jobs, check the severe weather warning page for any updates. For live tracking, the sefton weather radar on the Bureau’s site shows the band of light rain moving north-east.

How will conditions change this week?

High pressure is expected to build from the Bight by Thursday, clearing the cloud and lifting daytime highs. Overnight lows will remain mild — typical for Sefton’s location away from the coast.
