Check the live forecast above for Sydney’s conditions this week; expect a pattern of warm, humid days with the chance of a late shower as a coastal trough lingers.
What weather system is affecting Sydney this week?
A slow-moving trough over the Tasman Sea is drawing moist air onto the coast. This setup produces morning sunshine, afternoon cloud build-up and the risk of a brief storm, especially inland.
- Afternoon showers are most likely Tuesday through Thursday, then clearing by the weekend.
- Temperatures sit near average for late spring, with highs in the mid‑20s and mild overnight lows.
- Humidity will feel noticeable, particularly on still afternoons.
- Winds are light north‑easterly, freshening along the coast in the afternoon.
When will the weather settle?
The trough weakens from Friday, allowing a ridge to build. Saturday and Sunday look mostly fine with lighter winds and more sunshine.
- Friday still holds a slight chance of a morning shower, then clearing.
- The weekend offers the best chance for outdoor plans, though the UV index remains very high.
- If you need a longer outlook, see the 10‑day forecast for Sydney and the Sydney weather hub.
Will it rain every day this week in Sydney?
Not every day. The trough brings mainly afternoon showers on Tuesday to Thursday. Friday sees a lingering shower then clearing. The weekend should stay dry with sunny spells. Check the live forecast above for the latest timing.
How hot will it get this week?
Maximums will be in the mid‑20s – warm but not extreme. Overnight lows stay mild around 18–20°C. Humidity makes it feel warmer, especially before a shower. For a longer-range view, see the 10‑day forecast or other city outlooks.
Should I bring an umbrella?
Yes, for Tuesday to Thursday afternoons. The rain is usually short and showery, but worth having one handy. By Friday the chance drops, and the weekend is fine. For a 14‑day outlook, check the weather 10 days page.
