Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Coast Monitor Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
Check the live forecast above before heading to Lake St Clair. Weather here shifts fast due to its alpine location—expect cold, rain and strong winds even in summer, so pack layers and waterproof gear.
What should I expect from day-to-day weather?
Lake St Clair sits at 737 metres in Tasmania’s Central Highlands. Afternoon showers and sudden temperature drops are common year-round. Summer highs rarely exceed 15°C, while winter brings frost and snow to the higher trails. Wind picks up quickly along the lake, so check the hourly forecast before setting out on the Overland Track.
How does it compare to other Tasmanian places?
Hobart weather is milder and drier than Lake St Clair because of the altitude difference. Strahan weather on the west coast is wetter but less stormy. For a broader picture, see Australia’s weather hub. If a severe storm is forecast, severe weather warnings are issued for the region.
Can I hike the Overland Track in winter?
Yes, but only experienced walkers should attempt it. Snow and ice make trails slippery, daylight is short, and temperatures often drop below freezing at night. Check the 14 day forecast from BOM beforehand.
Is the weather at Lake St Clair the same as in Saint Clair, NSW?
No. Lake St Clair is in Tasmania, not NSW. For weather in Saint Clair NSW 10 days, refer to local NSW forecasts. The Tasmanian lake has a completely different alpine climate.
Where can I get hourly updates for today?
The Bureau of Meteorology provides lake st clair weather hourly observations and forecasts. The live forecast above also updates regularly. BOM Lake St Clair data is the most reliable source.
