Local Environmental Conditions
Diaz Beach lies roughly 340 km east of Cape Town. Indigenous forest, fynbos, and coastal scrub dominate the vegetation around Diaz Beach, with exposure varying between densely wooded sections and more open fairways, gardens, or built-up areas. The region's tourism and forestry operations adds to a landscape sustained by consistent rainfall throughout the year, consistent with the wider Garden Route forest belt.
Diaz Beach's Garden Route season opens in July with wattle and fynbos before indigenous forest and grass peak through September and October. The area's mild, year-round rainfall softens the seasonal peak, while tourism and forestry operations nearby adds to a landscape that keeps pollen present across a longer stretch of the year.

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