Local Environmental Conditions
Zeerust lies roughly 60 km northeast of Mahikeng. Zeerust's bushveld setting features acacia, mopane, and indigenous bushveld trees as the main pollen sources, with exposure varying between densely vegetated bushveld and more open, built-up sections. Surrounding savanna and platinum mining and tourism operations contribute substantial grass pollen through the summer rainfall season each year, consistent with the broader bushveld savanna environment.
Bushveld trees like acacia and mopane start the pollen year at Zeerust in August, handing over to grass as the main source from October through the humid summer months. The dry winter keeps levels low, while platinum mining and tourism operations nearby adds a further seasonal rhythm of its own, a pattern typical of the broader bushveld climate.

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