Local Environmental Conditions
Around 61% of the area near this location in Harrismith is open grassland, with some woodland and scrubland. So much tree cover makes trees an important source of pollen locally. There is plenty of grass pollen here too. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. A smaller weed peak follows from early summer into early fall. In warm, humid weather through summer, mold spores add to the mix, especially after rain. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Harrismith 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 Harrismith 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 Harrismith, 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.

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. |
