Local Environmental Conditions
At Nelspruit Extension, mopane and acacia thornveld define much of the bushveld vegetation, with denser tree cover found away from the built-up centre. The area's sugarcane, timber, and tourism operations shapes the wider savanna landscape, and grass pollen rises sharply through the warm, wet summer months that follow, consistent with the broader bushveld savanna environment.
Pollen from acacia and bushveld trees builds through August and September at Nelspruit Extension, tapering off as grass takes over from October through February. The subtropical climate ties pollen closely to the spring flush, and the area's sugarcane, timber, and tourism operations adds to the mix of vegetation and land use nearby, a pattern typical of the broader bushveld climate.

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