Local Environmental Conditions
Nearby, just around the area, the riverbank shelters acacia and eucalyptus, two trees whose pollen travels readily on the breeze. This area, in the surrounding area, has a stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen. The general pattern described here holds fairly steady across nearby areas with similar land cover.
The water-adjacent acacia and eucalyptus are early risers, arriving ahead of the rest of the season, cresting around late winter. Through late spring, grass pollen climbs steadily toward its December peak, with ragweed then rising to the fore from mid-February through April. Local weather swings can shift these windows slightly, but the overall order tends to hold.

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