Local Environmental Conditions
Richmond lies roughly 80 km west of Durban. At Richmond, Natal grassland and acacia thornveld define much of the surrounding vegetation, with eucalyptus common in older residential streets. The district's dairy and forestry farming operations shapes a wider landscape kept cooler than the lower-lying Highveld further inland, consistent with the wider KwaZulu-Natal Midlands landscape that shapes daily exposure across the wider Midlands district.
Pollen at Richmond builds from August as acacia and eucalyptus flower ahead of the Midlands grassland's grass pollen peak in November and December. The area's cooler, elevated climate and its dairy and forestry farming operations keep winter pollen low until the spring growing season begins, a pattern typical of the wider KwaZulu-Natal Midlands region.

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