Local Environmental Conditions
The heart of Stellenbosch is surrounded mainly by built-up land, which covers around 59% of the nearby area, with some woodland. Of the trees nearby, oak and olive are the ones that matter most for allergies. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak and olive are in full flower. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Plantain and pigweed flower through much of the warmer half of the year. The olive period in mid-spring is usually the most intense time of year here.

How often is the Stellenbosch pollen forecast updated?
The Stellenbosch pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Stellenbosch 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 Stellenbosch 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 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
