The weather in Johannesburg is one of its biggest attractions. For the most part, the city enjoys a mild and comfortable climate, though the summer months of December to February can bring uncomfortably hot and humid conditions. Luckily, from November to January, afternoon thunderstorms are frequent occurrences, providing relief from the heat in the form of heavy rain that disappears as quickly as it arrives. Winters, on the other hand, are generally dry and cold, particularly at night and in the mornings. Frost and hailstorms are occasional occurrences during the winter months. With conditions being at their driest in August, there is the risk of veld fires, but this rarely affects suburban residents.
