The winter months of May to September are dry, sunny with cool to warm temperatures generally reaching 68°F. However, once the sun goes down, temperatures drop significantly to as low as 41°F at night. Please note that very cold spells can occur and that weather is unpredictable but generally these temperature ranges do apply. During the summer months of October to April, the days are hot and sunny with highs reading 86°F in the morning with afternoon thunderstorms, particularly during the rainy season of mid November through mid March. Evenings and nights experience moderate temperatures in the 59°F range. Please note that in the lower lying areas such as the Zambezi Valley, Kariba and Victoria Falls, it is generally quite a bit warmer than the average and can be very hot in September and October in particular. The rainy season runs from November to March, although the Eastern Highlands are damp for most of the year.
