On 26 June 2026, pollen conditions in Knysna will be different from today, with artemisia at low levels and cypress increasing

According to the five-day outlook, artemisia and cypress pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

On 25 June 2026, Artemisia is the dominant pollen source in Knysna. cypress are also present but at lower levels. morus, myrtle, platanus, and urtica are not currently active.

Knysna's Garden Route lagoon season opens in July with wattle and coastal fynbos before yellowwood and stinkwood indigenous forest trees peak through September and October. Grass from surrounding farmland peaks through November, while the extensive Knysna Forest above contributes exceptional indigenous tree pollen diversity and the Knysna River lagoon creates a distinctive coastal pollen environment unlike most South African cities.

The Knysna 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 Knysna, 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.
