Warrawong’s weather today is typical for the Illawarra coast – mild with afternoon sea breezes. Check the live forecast above for the latest temperature, wind and chance of rain.
What is the typical climate in Warrawong?
Warrawong sits near the coast south of Sydney, so it gets warm summers and cool winters with reliable rainfall year‑round. Summer highs average around 25 °C, while winter afternoons reach about 16 °C. Rain falls fairly evenly across the months, and the area receives roughly 1300 mm each year. South‑easterly winds dominate, especially in the warmer months, pushing moist air inland and often triggering afternoon showers.
How does the ocean affect Warrawong’s weather?
Being only a few kilometres from the Tasman Sea, Warrawong’s temperatures are moderated by sea breezes. In summer these breezes keep afternoons cooler than western suburbs, but they also bring humidity. Fog is uncommon, though the coast can produce low cloud or drizzle during onshore flows. Surf conditions and coastal wind matter for swimmers and boaters – check the live forecast above and the local severe weather warnings if a southerly change is due.
Does Warrawong get thunderstorms?
Yes. Thunderstorms are most common from late spring to early autumn, driven by inland heating and coastal convergence. The Australia weather hub and BOM radar track them for the Illawarra.
How accurate is the forecast for Warrawong?
Local forecasts are quite reliable for temperature and wind direction due to the stable coastal regime. Hourly and radar updates (see Sydney weather for the broader picture) give good short‑term detail, especially for showers.
When is the best time to visit Warrawong?
Late spring (October‑November) and early autumn (March‑April) offer warm days, lower humidity and fewer showers. Winter is cool but sunny, while summer can be humid with occasional storms.
