Local Environmental Conditions
The area around this location in Johannesburg is densely built up, with some open grassland. Locally, planted trees and mown lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Then come the grasses, strongest in mid-spring and fading by early fall. A smaller weed peak follows from early summer into early fall. In warm, humid weather from late spring into late summer, mold spores add to the mix, especially after rain. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
