Local Environmental Conditions
Delmas lies roughly 240 km west-southwest of Nelspruit. Eucalyptus, acacia, and open grassland define the vegetation around Delmas, with exposure shifting between leafier residential pockets and busier commercial corridors nearby. The surrounding area's coal mining and power station operations shapes much of the land beyond the town, adding grass and dust to the seasonal pollen mix each summer, consistent with the wider Highveld plateau environment.
Pollen at Delmas builds from August as acacia and eucalyptus flower, with Highveld grass taking over through October and November. The elevated plateau's dry winter suppresses production until the spring rains arrive, and the area's coal mining and power station operations adds a distinctive local backdrop to the grass-dominated summer pollen season, a pattern typical of the wider Highveld region.

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