When's the best time to visit Clare Valley?
While Clare Valley enjoys reasonably great weather all year, but autumn (March to May) is a glorious time in the region. The weather is warm (think temperatures in the mid-20s) and smaller crowds. You could also align your trip with the Clare Valley Gourmet Week, Australia’s longest-running traditional wine and food festival, at the end of May.
Another great time to visit is spring (September to November). The countryside and pastures are lush and green thanks to the winter rains, average temperatures rise to the low 20s, and flowers and wildlife flourish.
