Local Environmental Conditions
Nelspruit's Mpumalanga Lowveld Crocodile River setting features subtropical trees, mango, and papaya as the main tree pollen sources alongside Lowveld bushveld, with exposure varying between the wooded Crocodile River valley and the more built-up commercial corridors along Bester Street. The Crocodile River corridor is a particularly significant local source, while the surrounding Lowveld bushveld contributes distinctive subtropical pollen quite different from Highveld cities throughout the season.
Nelspruit's Mpumalanga Lowveld season opens in August with subtropical trees and mango before grass from surrounding Lowveld bushveld and farmland peaks through November and December. The Crocodile River corridor contributes locally significant riparian pollen, while the surrounding Lowveld bushveld contributes distinctive subtropical tree pollen quite different from Highveld cities and the warm Lowveld climate advances the season compared to higher altitude Mpumalanga cities.

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. |
