Local Environmental Conditions
The area around this location in Johannesburg is densely built up, with some woodland. Among allergenic trees nearby, olive is the main source. Grasses are a major source, with pigweed adding to the weed pollen load. Around here, street trees, parks and lawns are the main sources in the built-up parts.
Tree pollen peaks in mid-spring, when the weather warms to around 20°C and olive is in full flower. Grasses take over in mid-spring and keep pollen in the air into early fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Warm, damp weather from late spring into late summer also raises mold spore levels.

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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
