Local Environmental Conditions
Uitenhage's Eastern Cape Sundays River setting features acacia, eucalyptus, and Port Jackson wattle as the main tree pollen sources alongside Eastern Cape thicket. Exposure varies between the wooded Swartkops River corridor and the more built-up industrial and commercial corridors, while the Eastern Cape thicket on the surrounding hills contributes distinctive local pollen and the flat valley floor allows pollen to disperse widely throughout.
Uitenhage's Eastern Cape season opens in July with Port Jackson wattle and rooikrans before Eastern Cape thicket and grass peak through September and October. The Swartkops River corridor contributes locally significant riparian pollen, while the flat valley setting allows pollen to disperse widely and the invasive wattle is a particularly significant early local pollen source throughout this Eastern Cape industrial city.

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