Local Environmental Conditions
Erinvale Golf Club's Western Cape Somerset West setting features fynbos, oak, and introduced bent grass as the main pollen sources across the course, with exposure varying between the fynbos-bordered fairways and the more open False Bay-facing sections. Surrounding Cape fynbos and the Hottentots Holland Mountain slopes contribute distinctive Cape pollen, while the Mediterranean climate concentrates the pollen season in spring from August through November and the False Bay position means onshore winds can periodically disperse pollen.
Beneath the Helderberg mountains, Erinvale's fynbos and vineyard surroundings flower through August and September, a few weeks ahead of the drier summer that follows from November. The mountain backdrop provides some shelter from the strongest Cape Doctor gusts compared to more exposed False Bay courses.

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