Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in US as well as at Johannesburg, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

The year in Johannesburg

Johannesburg experiences a summer rainy season, with most rainfall occurring from November to February. However, January tends to have the highest rain days. Please consider these factors when planning your visit.

Busiest	early Nov to late Feb — This period coincides with the summer season in Johannesburg, attracting many tourists with warm weather and festive events.
Quieter, still good	early Mar to late May — These months offer mild weather and fewer tourists, often resulting in better accommodation rates and less crowded attractions. early Sep to late Oct — The transition to warmer weather during these months can be pleasant, with manageable tourist levels.
Watch out for	extreme heat

Written by a language model from the climate figures above. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe.
