Local Environmental Conditions
Delareyville lies roughly 90 km south of Mahikeng. At Delareyville, acacia, eucalyptus, and Highveld grassland dominate the local pollen picture, with exposure varying between wooded residential streets and more open, built-up parts of town. Surrounding maize, sunflower, and grain farming operations adds further texture to the landscape, while farmland nearby contributes grass pollen through the summer rainfall months, consistent with the wider Highveld plateau environment.
Delareyville's Highveld season opens in August with acacia and eucalyptus before grass from the surrounding grassland peaks through October and November. The dry winter months keep pollen low, while maize, sunflower, and grain farming operations nearby shapes the local landscape, and the summer rainfall pattern concentrates the main season into spring and early summer.

How often is the Delareyville pollen forecast updated?

Does pollen in Delareyville 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 Delareyville 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 Delareyville, 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. |
