Local Environmental Conditions
Beaufort West lies roughly 420 km east-northeast of Cape Town. At Beaufort West, sparse Karoo scrub and camel thorn acacia define most of the surrounding vegetation, with irrigated gardens providing the only real greenery within town. The area's sheep farming and small-town activity shapes a wider landscape where pollen sources remain thin for most of the year, consistent with the wider semi-arid Karoo landscape.
At Beaufort West, the Karoo's low rainfall limits pollen production to a brief spring peak. Acacia and hardy scrub flower from August, with grass following through September and October, after which the dry summer heat and the area's sheep farming and small-town activity keep further pollen release minimal until spring returns, a pattern typical of the wider semi-arid Karoo interior.

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