Local Environmental Conditions
De Aar lies roughly 220 km south-southwest of Kimberley. De Aar's semi-arid Karoo setting features camel thorn acacia, hardy scrub, and sparse grassland as the main pollen sources, with exposure varying between limited irrigated green spaces and the more open, arid surrounding landscape shaped by diamond prospecting history and stock farming, consistent with the wider semi-arid Karoo landscape that shapes daily exposure across the surrounding plains.
Karoo scrub and acacia mark a brief pollen season at De Aar from August through October, tied closely to the spring growing period after the dry winter. The area's diamond prospecting history and stock farming and generally low rainfall mean pollen stays low outside this narrow window most years, a pattern typical of the wider semi-arid Karoo interior.

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