Port St Johns lies roughly 450 km northeast of Gqeberha. Port St Johns's Eastern Cape setting features acacia, Port Jackson wattle, and Eastern Cape thicket as the main pollen sources, with exposure varying between wooded green spaces and more built-up commercial and residential areas shaped by mixed farming and light industrial activity, consistent with this transitional Eastern Cape vegetation zone that shapes daily exposure across the wider district.

Does pollen in Port St Johns 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 Port St Johns 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 Port St Johns, 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.
