Riebeeckstad lies roughly 140 km north-northeast of Bloemfontein. Riebeeckstad's Highveld setting features eucalyptus, acacia, and introduced oak as the main tree pollen sources alongside open grassland, with exposure varying between greener residential areas and the more built-up corridors. Surrounding grassland and farmland contribute substantial grass pollen through summer, a mix shaped locally by gold mining and processing operations, consistent with the wider Highveld plateau environment.

How often is the Welkom pollen forecast updated?

Does pollen in Welkom 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 Welkom 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 Welkom, 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.
