Local Environmental Conditions
Alexandria lies roughly 80 km east-northeast of Gqeberha. Acacia, Port Jackson wattle, and dense Eastern Cape thicket dominate the vegetation around Alexandria, with exposure varying between thicket-covered valleys and more open, cleared or built-up parts of town. The area's mixed farming and light industrial activity adds to a landscape supporting a varied mix of species, consistent with this transitional Eastern Cape vegetation zone.
Alexandria's Eastern Cape season opens in July with acacia and Port Jackson wattle before thicket and grass peak through September and October. The transitional climate between winter- and summer-rainfall zones, along with mixed farming and light industrial activity nearby, produces a moderate, fairly evenly spread pollen season across the year, a pattern typical of this transitional Eastern Cape climate zone.

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