Welkom's Free State Highveld gold mining setting features acacia, eucalyptus, and Highveld grassland as the main pollen sources, with exposure varying between the limited residential green spaces and the more built-up mining, commercial, and planned township corridors. The Vet River tributary corridor provides locally significant green space, while the surrounding Highveld grassland contributes substantial grass pollen and the planned apartheid-era town layout creates relatively uniform pollen distribution throughout.

When is pollen season in Welkom?
Welkom's Free State Highveld gold mining season opens in August with acacia and eucalyptus before grass from surrounding Highveld grassland peaks through November and December. The Vet River tributary corridor contributes locally significant riparian pollen, while the dry winter months suppress most pollen production and the summer rainfall pattern concentrates the main season in spring and early summer throughout this planned Free State gold mining city.
How often is the Welkom pollen forecast updated?

The Welkom pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.
