From August, Cloetesville moves through its short Cape spring pollen window, fynbos and oak first, then grass through September and October, all playing out against the backdrop of vineyard and wine estate operations. The reliable southeasterly wind does much of the work keeping levels down outside this window. This mirrors the broader seasonal pattern seen across much of the Cape fynbos belt.

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

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.

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 Stellenbosch, 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.
