Local Environmental Conditions
Florida lies roughly 10 km west of Johannesburg. Around Florida, the vegetation is a patchwork of eucalyptus, acacia, and introduced oak in the older streets, thinning out into open Highveld grassland once you leave the built-up core, with government, finance, and commercial operations occupying much of that outer land. This split between wooded town and open plateau shapes exposure block by block.
Grass and acacia dominate the pollen picture at Florida, with the season opening in August and peaking through October and November as Highveld grassland flowers. The dry winter months are largely pollen-free, while the surrounding government, finance, and commercial operations defines much of the land beyond the town itself, a pattern typical of the wider Highveld region.

When is pollen season in Johannesburg?
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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
