Union Buildings lies roughly 50 km north-northeast of Johannesburg. Union Buildings's tree cover leans heavily on eucalyptus, acacia, and introduced oak, interspersed with open Highveld grassland that dominates beyond the built-up centre. Nearby government, finance, and commercial operations shapes the wider landscape, while exposure to grass pollen rises sharply once the summer rains reach the surrounding farmland, consistent with the wider Highveld plateau environment.

How often is the Pretoria pollen forecast updated?
The Pretoria pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Pretoria 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 Pretoria 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 Pretoria, 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.
