Live satellite rain over Johannesburg

Satellite rain estimate around Johannesburg, observed 13:20 SAST
The area about 165 km around Johannesburg, observed 13:20 SAST — roughly 20 minutes old. The estimate is about four kilometres per pixel and can miss light rain under low cloud, so an empty-looking picture over Johannesburg is not a promise that it is dry — check the hour-by-hour table below as well. Satellite rain estimate: contains modified EUMETSAT Meteosat data 2026, processed by EUMETSAT’s H SAF and made available under CC BY 4.0. It is an estimate from satellite, not weather radar.

How rain works in this part of the country

The Highveld is a summer-rainfall region: the great majority of the year's rain falls between October and March, and it arrives as convective afternoon and evening thunderstorms rather than all-day drizzle. A wet summer day here is usually a bright morning followed by a violent two-hour storm. From May to August it is normal for weeks to pass with no measurable rain at all.
