Local Environmental Conditions
Franschhoek lies roughly 60 km east of Cape Town. Franschhoek's plant life leans on fynbos scrub alongside introduced oak and pine, with exposure shifting between these green pockets and the more built-up parts of the area. The surrounding vineyard and wine estate operations adds further variety, and fynbos remains the dominant spring pollen source most years, consistent with the broader Cape fynbos biome.
Fynbos scrub and oak dominate the pollen calendar at Franschhoek, opening in August and building toward a grass-driven peak in September and October. The area's vineyard and wine estate operations contributes further seasonal variation, while the long, dry Cape summer that follows keeps levels consistently low until winter returns, a pattern typical of the broader Cape fynbos biome.

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