Local Environmental Conditions
Zwartkop Country Club lies roughly 40 km north-northeast of Johannesburg. Grassland, acacia, and eucalyptus make up most of the vegetation at Zwartkop Country Club, with denser tree cover in older residential streets giving way to open country beyond town. The district's government, finance, and commercial operations adds to the mix, and grass pollen becomes the dominant source once summer rains set in, consistent with the wider Highveld plateau environment.
Zwartkop Country Club sees its first tree pollen from acacia and eucalyptus in August, with Highveld grass following as the dominant source through October and November. The dry winter keeps things quiet until then, and the district's government, finance, and commercial operations means exposure varies between greener pockets and more built-up ground, a pattern typical of the wider Highveld region.

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