Local Environmental Conditions
Hornlee lies roughly 420 km east of Cape Town. Hornlee's vegetation draws on indigenous forest, fynbos, and coastal scrub, with denser tree cover found away from the built-up coastal strip. Surrounding tourism and forestry operations shapes the wider landscape, while consistent year-round rainfall keeps a broad mix of species contributing pollen for months at a time, consistent with the wider Garden Route forest belt.
At Hornlee, the Garden Route's mild climate spreads the pollen season out from July through October, starting with wattle and fynbos before forest and grass take over. The surrounding tourism and forestry operations adds further variety to the vegetation, keeping the season gentler than the sharper Cape peak further west, a pattern typical of the wider Garden Route climate.

How often is the Knysna pollen forecast updated?
The Knysna pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Knysna 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 Knysna 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 Knysna, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
