Local Environmental Conditions
Woodland makes up around 39% of the area near the center of Grabouw, with a good deal of built-up land and some open grassland. Trees are an important local pollen source, given how much woodland surrounds the area. Grasses are also a significant pollen source here. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Tree pollen comes first, peaking in early spring. Then come the grasses, strongest in late spring and fading by early fall. A smaller weed peak follows from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

Does pollen in Grabouw 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 Grabouw 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 Grabouw, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
