Local Environmental Conditions
Benoni's East Rand Highveld setting features eucalyptus, acacia, and weeping willow as the main tree pollen sources alongside Highveld grassland, with exposure varying between the greener Lakeside residential areas and the more built-up commercial and industrial corridors. The Kleinfontein Lake and Rynfield corridors provide locally significant green space, while the surrounding Highveld grassland contributes substantial grass pollen during summer.
Benoni's East Rand Highveld season opens in August with eucalyptus and acacia before grass from surrounding Highveld grassland peaks through November and December. The Kleinfontein Lake corridor contributes locally significant riparian pollen, while the dry Highveld winter suppresses most pollen production and the summer rainfall pattern concentrates the main season in spring and early summer throughout this East Rand city.

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