Local Environmental Conditions
Midrand's Johannesburg-Tshwane metropolitan corridor setting features jacaranda, eucalyptus, and acacia as the main tree pollen sources, with exposure varying between the greener residential developments and the rapidly expanding commercial and business park corridors along the N1 highway. The Jukskei River corridor provides locally significant green space, while the urban heat island of the metropolitan corridor advances pollen timing slightly compared to surrounding areas.
Midrand's Johannesburg-Tshwane metropolitan corridor season opens in August with jacaranda and eucalyptus before grass from surrounding Highveld grassland peaks through October and November. The jacaranda flowering in October contributes a locally significant and iconic tree pollen source, while the Jukskei River corridor contributes locally significant riparian pollen and the metropolitan urban heat island slightly advances seasonal timing.

When is pollen season in Midrand?
How often is the Midrand pollen forecast updated?
The Midrand pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Midrand 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 Midrand 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 Midrand, 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. |
