Local Environmental Conditions
Brits's North West Highveld Magalies River setting features acacia thornveld, eucalyptus, and Bushveld trees as the main pollen sources, with exposure varying between the wooded Magalies River corridor and the more built-up commercial corridors around the town centre. The Magalies River corridor is a particularly significant local source, while the Magaliesberg Mountains above create elevation-based pollen gradients and the surrounding Bushveld contributes distinctive thornveld pollen throughout the season.
Brits's North West Highveld Magalies River season opens in August with acacia thornveld and eucalyptus before grass from surrounding Bushveld farmland peaks through November and December. The Magalies River corridor contributes locally significant riparian pollen, while the Magaliesberg Mountains above create elevation-based pollen gradients between the highland and the valley town below throughout the season.

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