Randfontein's West Rand Highveld mining setting features eucalyptus, acacia, and introduced grassland as the main pollen sources, with exposure varying between the limited residential green spaces and the more built-up mining, commercial, and industrial corridors. The Mooi River tributary corridor provides locally significant green space, while the surrounding Highveld grassland contributes substantial grass pollen and the historical gold mining landscape limits native vegetation considerably throughout.

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

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

Does pollen in Randfontein 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 Randfontein 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 Randfontein, 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.
