Harrismith's Free State Drakensberg foothills setting features Drakensberg highland grassland, acacia, and eucalyptus as the main pollen sources, with exposure varying between the Platberg Mountain above and the more built-up commercial corridors in the valley town. Platberg is a particularly significant local pollen source, while the surrounding eastern Free State Highveld farmland contributes substantial grass pollen and the dramatic mountain setting creates pronounced elevation-based pollen gradients throughout.

How often is the Harrismith pollen forecast updated?

Does pollen in Harrismith 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 Harrismith 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 Harrismith, 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.
