Local Environmental Conditions
Jeffreys Bay lies roughly 60 km west of Gqeberha. Jeffreys Bay's vegetation draws on acacia, wattle, and dense thicket typical of the Eastern Cape, with exposure shifting between valley cover and more open ground nearby. Surrounding mixed farming and light industrial activity adds further variety to a landscape supported by both winter and summer rainfall patterns, consistent with this transitional Eastern Cape vegetation zone.
At Jeffreys Bay, acacia and wattle open the Eastern Cape pollen season in July, with thicket vegetation and grass building to a peak by September and October. The transitional rainfall pattern and the surrounding mixed farming and light industrial activity together keep the season spread fairly evenly across several months, a pattern typical of this transitional Eastern Cape climate zone.

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

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
