Local Environmental Conditions
Centurion's Tshwane metropolitan setting features jacaranda, eucalyptus, and acacia as the main tree pollen sources, with jacaranda being a locally iconic and seasonally significant source in late spring. Exposure varies between the greener residential suburbs and the more built-up commercial corridors along Centurion Mall, while the Hennops River corridor provides locally significant riparian vegetation pollen throughout the season.
Centurion's Tshwane metropolitan Highveld season opens in August with jacaranda and acacia before grass from surrounding Highveld grassland peaks through October and November. The jacaranda flowering in October is a locally iconic and significant tree pollen event, while the Hennops River corridor contributes locally significant riparian pollen and the summer rainfall pattern concentrates the main season in spring and early summer.

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