How to connect?

Johannesburg's suburban woodland and green corridors, including the Braamfontein Spruit and Joubert Park, feature acacia, eucalyptus, and introduced oak as the main tree pollen sources, with exposure varying between greener residential areas and the more built-up city centre. Surrounding Highveld grassland contributes substantial grass pollen, with the summer rainfall climate concentrating grass pollen production from November to March when thunderstorms can trigger asthma events.

When is pollen season in Johannesburg?
Johannesburg's pollen season follows the Southern Hemisphere spring and summer pattern, opening with tree pollen from acacia and introduced species from August through October. Grass pollen from the Highveld grassland dominates from October through March, coinciding with the summer rainfall season. Thunderstorms during November and December can trigger thunderstorm asthma events when grass pollen grains rupture and release allergenic particles.
How often is the Johannesburg pollen forecast updated?

The Johannesburg pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Johannesburg come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Johannesburg based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Johannesburg, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
