Local Environmental Conditions
Mitchells Plain's Cape Flats setting features fynbos scrubland, Port Jackson wattle, and urban street trees as the main pollen sources, with exposure varying between the limited residential green spaces and the more open fynbos remnants on the Cape Flats. The flat, sandy setting allows pollen to disperse widely and the invasive wattle contributes substantially during late winter and spring.
Mitchells Plain's Cape Flats pollen season opens in July with Port Jackson wattle before fynbos and restio pollen peak through August and September. Grass from surrounding Cape Flats vegetation peaks through October and November, while the flat, wind-exposed setting allows pollen to disperse widely and the strong Cape southeasterly winds frequently interrupt and disperse pollen across the city throughout the spring season.

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