Local Environmental Conditions
Oudtshoorn's Klein Karoo Olifants River valley setting features acacia, olive, and Karoo scrub as the main pollen sources, with exposure varying between the Swartberg and Outeniqua Mountain slopes above and the more built-up commercial corridors in the valley below. The Olifants River corridor provides locally significant riparian vegetation, while the surrounding Klein Karoo semi-arid landscape contributes distinctive succulent scrub pollen quite different from the coastal Garden Route cities.
Oudtshoorn's Klein Karoo valley season opens in August with acacia and olive before Karoo scrub and grass from surrounding semi-arid farmland peaks through October and November. The Olifants River corridor contributes locally significant riparian vegetation, while the Swartberg and Outeniqua Mountain slopes above create elevation-based pollen gradients between the highland fynbos and the more open semi-arid valley floor below throughout.

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. |
