How to connect?

Bloemfontein's Free State Highveld setting features acacia, eucalyptus, and weeping willow as the main tree pollen sources alongside mixed Highveld grassland. Exposure varies between the greener Naval Hill and residential areas and the more built-up commercial corridors, while the flat, open Highveld landscape allows grass pollen from surrounding farmland to disperse very widely throughout the city.

When is pollen season in Bloemfontein?
Bloemfontein's Free State Highveld season is strongly driven by the summer rainfall pattern, with acacia contributing from August before grass from surrounding Highveld farmland peaks intensely through October and November. The flat, open Highveld landscape allows pollen to disperse very widely, while the dry winter months of June and July suppress most pollen production across this semi-arid Free State capital.
How often is the Bloemfontein pollen forecast updated?

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

Does pollen in Bloemfontein 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 Bloemfontein 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 Bloemfontein, 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.
