Local Environmental Conditions
Anglo-Boer War Museum's Highveld setting features eucalyptus, acacia, and introduced oak as the main tree pollen sources alongside open grassland, with exposure varying between greener residential areas and the more built-up corridors. Surrounding grassland and farmland contribute substantial grass pollen through summer, a mix shaped locally by maize, sunflower, and grain farming operations, consistent with the wider Highveld plateau environment.
Dust and dry air define the Anglo-Boer War Museum winter until acacia and eucalyptus break the pattern in August, setting up a grass-dominated October-November peak amid maize, sunflower, and grain farming operations. Once the plateau's summer thunderstorms establish themselves, pollen and airborne dust both settle down considerably. This mirrors the broader seasonal pattern seen across much of the Highveld region.

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