Local Environmental Conditions
Piet Retief (eMkhondo) lies roughly 170 km south of Nelspruit. Piet Retief (eMkhondo) carries the typical Highveld mix: acacia and eucalyptus lining residential streets, grassland taking over past the edge of town, and coal mining and power station operations filling out the wider landscape beyond. Pollen exposure tracks this pattern closely, higher near remaining tree cover, lower on the open grass plains. This pattern holds true across most of the surrounding Highveld plateau.
August ushers in acacia and eucalyptus pollen at Piet Retief (eMkhondo), giving way to a Highveld grassland peak by October and November, framed by the area's coal mining and power station operations. Winter stays largely pollen-free until the spring rains break the dry spell. This mirrors the broader seasonal pattern seen across much of the Highveld region.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Piet Retief (eMkhondo) based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

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. |
