The best time to go to Cosmo Newbery is during the cooler, drier months from April to October.
During this period, the weather is more comfortable for outdoor activities, with daytime temperatures typically ranging from 20 to 28 degrees Celsius. This is ideal for exploring the surrounding Goldfields-Esperance region and engaging in activities like bushwalking or visiting local Aboriginal cultural sites.
Families often find these months more suitable for travel, as the milder temperatures make it easier to manage children during excursions. The lower humidity also contributes to a more pleasant experience overall.
For travellers interested in the natural landscape, this season offers clearer skies and less chance of rain, which is great for stargazing or photography.
