Local Environmental Conditions
The nearest stream or river hosts acacia and eucalyptus, two of the most allergenic early-season trees; this sits near this part of town. Parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen; this sits in the surrounding area. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Near the bank, acacia and eucalyptus lead the seasonal calendar, climbing steadily from late winter into September. Grass pollen builds through late spring and peaks in December, with ragweed then rising to the fore from mid-February through April. Regional pollen monitoring generally reflects this same pattern across nearby areas. Small variations in local weather can nudge these windows a few days in either direction.

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