Local Environmental Conditions
Rustenburg's parks feature acacia, eucalyptus, and indigenous bushveld species as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding North West Province bushveld and farmland contribute substantial grass and scrub pollen, with the summer rainfall climate concentrating grass pollen production from November to March.
Rustenburg's pollen season follows the Southern Hemisphere spring and summer pattern, opening with tree pollen from acacia and eucalyptus from August through October. Grass pollen from surrounding North West Province bushveld dominates from October through March, coinciding with the summer rainfall season. Thunderstorms during the peak grass season can periodically concentrate pollen, while the dry winter from May to August is largely free of significant grass pollen.

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