Local Environmental Conditions
Three Rondavels lies roughly 50 km north-northwest of Nelspruit. Acacia thornveld, mopane, and indigenous bushveld species dominate the vegetation around Three Rondavels, with exposure varying between wooded bushveld pockets and more open, cleared areas. Surrounding sugarcane, timber, and tourism operations adds further grass pollen once summer rains begin, while the warm subtropical climate keeps tree pollen present for months, consistent with the broader bushveld savanna environment.
Three Rondavels's bushveld season opens in August with acacia and mopane before grass from the surrounding savanna peaks through October and into summer. The dry winter keeps pollen low, while sugarcane, timber, and tourism operations shapes the surrounding land, and the onset of summer rains drives a strong grass pollen flush from November.

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