Before you visit Kangaroo Island, make sure you're aware of the weather conditions to expect. Kangaroo Island is a beautiful place to visit year-round, but it is important to pack accordingly.
Kangaroo Island has a Mediterranean climate: typically warm to hot dry summers (December-February) with very low humidity; and cool, mild winters (June-August). Our spring (September-November) and autumn (March-May) are true shoulder seasons where days can be more like winter or summer or something in between! We have never seen snow on the Island and slight frosts occur rarely and only in the central part of the Island.

A majority of our rainfall occurs from April through September and typically falls in fast moving fronts scudding across the Southern Ocean. The exception to this is when we get a cyclonic system coming down from the Tropics and across the Outback when it is warm, wet and humid. These conditions occur mainly in summer every 3-4 years.

Despite “averages”, because of our proximity to an enormous and dynamic ocean to our south, we can get cold and windy conditions in any month. The UV light in the mid-latitudes of the Southern Hemisphere is extreme – SPF 50+ is part of our everyday routine when venturing outside. We are an outdoor experience provider and suggest you bring at least one warm layer, a waterproof jacket and a sunhat so you will be prepared and comfortable whatever the conditions happen to be.
