Cape Town, on the Cape Peninsula, has a Mediterranean climate with dry summers and wet winters. Seasons are well defined, with winter, between May and August, being influenced by a series of cold fronts that cross the Peninsula from the Atlantic Ocean. Winters are characterised by heavy rain, particularly on the mountain slopes, strong north-westerly winds, and low temperatures. In summer the weather in Cape Town is warm and dry, but the idyllic sunny weather is often punctuated with strong south easterly winds.
