Randburg's suburban setting in northern Johannesburg features acacia, eucalyptus, and introduced oak as the main tree pollen sources in parks and along streets, with exposure varying between green areas and the more built-up areas. Surrounding Gauteng highveld grassland contributes substantial grass pollen, with the summer rainfall climate concentrating exposure from November to March.

When is pollen season in Randburg?
Randburg's pollen season follows the Southern Hemisphere spring and summer pattern, opening with tree pollen from acacia, eucalyptus, and introduced oak from August through October. Grass pollen from surrounding Highveld grassland dominates from October through March, coinciding with the summer rainfall season. Thunderstorms during the peak grass season can periodically concentrate pollen, while the dry Highveld winter from May to August is largely free of significant grass pollen.
How often is the Randburg pollen forecast updated?

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

Does pollen in Randburg 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 Randburg 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 Randburg, 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.
