Local Environmental Conditions
Steytlerville lies roughly 140 km west-northwest of Gqeberha. Camel thorn acacia, hardy Karoo scrub, and sparse grassland dominate the vegetation around Steytlerville, with exposure varying between the town's limited irrigated gardens and the vast, arid surrounding plains. The region's sheep and ostrich farming operations adds to a landscape defined largely by low rainfall, consistent with the wider semi-arid Karoo landscape.
Steytlerville's semi-arid Karoo season is compressed into a short spring window, with camel thorn acacia and Karoo scrub opening from August before grass peaks through September and October. The dry climate, sheep and ostrich farming operations nearby, and sparse vegetation keep overall pollen levels low for most of the year, a pattern typical of the wider semi-arid Karoo interior.

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