Although the total amount of rainfall is low (2-4 mm per month), the summer months (January, February, December) and November see quite a few days with light rain (12-17 days), so a compact umbrella or a light raincoat will be very handy. Evenings can be slightly cooler (lows around 14-15°C), so a light sweater or cardigan is worth bringing.

During this time of year, you'll need warmer items: sweaters, fleece jackets, jeans or thick trousers, and a mid-season jacket. Winter in Sandton is the driest period, with almost no precipitation, so the main focus should be on warm, comfortable clothing for dry weather.
