Local Environmental Conditions
Cango Caves lies roughly 360 km east of Cape Town. At Cango Caves, yellowwood and indigenous forest trees mix with fynbos scrub across a landscape shaped as much by dense woodland as by open, cleared ground near town. The area's tourism and forestry operations contributes further variety, aided by the Garden Route's mild, damp climate, consistent with the wider Garden Route forest belt.
Pollen builds gradually at Cango Caves from July, with wattle and coastal fynbos giving way to forest and grass through September and October. Consistent year-round rainfall moderates the peak, and the district's tourism and forestry operations contributes to a mix of vegetation that rarely lets pollen levels spike sharply, a pattern typical of the wider Garden Route climate.

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