Check the live forecast above for Cattai’s current conditions. Expect a mild, humid morning with possible afternoon showers — typical for this Hawkesbury Valley spot, where temperatures often sit a few degrees cooler than Sydney’s city centre due to the river influence.
What’s the temperature range today?
The live forecast above shows a high near 28°C and a low around 18°C, with humidity hovering above 60%. The river breeze can drop feels-like temps by 2–3°C in the early hours, so a light jacket may help before 9 am.
Will it rain this week?
Patchy rain is likely Tuesday and Wednesday from a coastal trough. The 10-day forecast suggests 5–10 mm total, mostly light. Check the Sydney Weather page for broader timing — Cattai often sees a 30-minute lag behind city showers.
How does Cattai compare to Wisemans Ferry?
Cattai sits slightly upstream and inland, so it’s a degree or two warmer than Wisemans Ferry weather forecast 14 days shows. River fog lifts faster here — by 8 am most days. For hourly detail, check the cattai weather hourly updates on our Australia weather hub.
Does Cattai get afternoon storms?
Yes, about 40% of summer days. They form over the Blue Mountains and drift east, hitting Cattai between 3 and 5 pm. The cattai weather 14 day forecast usually flags these 48 hours out.
What’s the best time for a river walk?
Early morning, before 10 am. Humidity stays under 60%, and the track along Cattai Creek is shaded. Afternoon temps can spike 5°C higher than the Sydney Weather page shows for the city.
Should I pack a raincoat?
Yes, especially if the cattai weather live forecast above shows 30% or more rain. A light shell is enough — downpours here rarely last longer than 20 minutes.
