Clare Valley Tours

Clare Valley Weather

The weather decides how your day in the valley feels. Summer heat makes the Riesling Trail hard work, and winter rain moves you indoors. Planning wine tours Clare Valley? Pick your month first, then the day.

You spend a Clare Valley day outdoors between cellar doors, on the trail or on a walk. In January the average high at Clare is 30.5 °C, and rain falls on about three days. In July the high is 13.0 °C, with rain on about ten days. Both work, but they call for different days.

Heat hits bikes and walkers hardest, and the park service tells you to avoid walking in the hottest part of the day. Rain matters most on the same trails. A guided day in an air-conditioned vehicle copes with both. The figures below are the Bureau of Meteorology's averages for Clare High School, 1994 to 2026.

The valley is higher than most of South Australia's wine country, so nights stay cool even in summer. Pack a layer whatever the month.

Festivals through the year

The Clare Valley Gourmet Festival calls itself Australia's longest running wine and food festival. If you want to go, book your bed as soon as the dates are out. Clare Valley Tourism also lists the Skilly Valley Way in early October on its What's On calendar.

Fire danger days and closures

Hot, dry days bring fire danger ratings, and they can change your plans. Spring Gully Conservation Park closes on Catastrophic Fire Danger days and may close on Extreme days. The Clare Valley Wine, Food and Tourism Centre also closes on Catastrophic Fire Days.

On a high fire danger day: check the rating with the Country Fire Service, or call its Bushfire Information Hotline on 1800 362 361. Then swap the walk for tastings indoors, using Clare Valley wineries.

Best time of day

In summer, go early. At 3pm in January, Clare averages 28.7 °C, so ride or walk in the morning and save the tasting rooms for the afternoon. The valley days collect you at 10am and bring you back at about 4:30pm.

In winter, the light goes early and the evenings are cold. Plan your ride for the middle of the day. At Spring Gully, kangaroos and euros graze in the evenings, so walk late in the day if you want to see them.
