Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Australia Pulse Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
The live forecast above shows Kogarah’s current temperature and conditions; expect a daytime range of 20–24°C with a 40% chance of a coastal shower. This means a mild, partly cloudy day typical of late spring in southern Sydney.
What is driving Kogarah’s weather today?
A high-pressure system over the Tasman Sea is directing a light easterly airflow across the Sydney basin. That onshore flow keeps Kogarah a degree or two cooler than inland suburbs. Humidity sits near 65%, and the UV index will reach moderate levels by midday.
When will conditions change?
Late Wednesday a trough approaches from the west, lifting the shower chance to 60% overnight. Thursday then turns warmer and more humid — expect the temperature to nudge 28°C before a possible afternoon thunderstorm. Friday returns to a sunny, milder pattern as the ridge rebuilds.
Why is Kogarah often cooler than western Sydney?
Kogarah’s proximity to Botany Bay means a sea breeze arrives by late morning, cutting the temperature by 3–5°C compared with Penrith or Richmond. The same onshore flow also lifts humidity slightly but moderates extreme heat.
Does Kogarah get thunderstorms?
Yes, mainly in spring and summer. Thunderstorms develop when a trough moves over humid air from the coast. Gusty winds and heavy rain are possible, but severe storms are less frequent than in inland NSW because the sea breeze disrupts storm organisation.
When is the best time to visit Kogarah Beach?
Late morning to early afternoon on a day with a light north-easterly wind (live forecast above shows wind direction). Calm conditions and low swell make swimming safest, but always check the local beach report for rips. Summer weekends draw larger crowds.
