Local Environmental Conditions
Located not far from here, this area has river oak lines the bank, contributing some of the season's more persistent wind-borne pollen. Maintained parkland where turf grass and ornamental plane trees add to the local pollen mix, just outside the immediate area. The broader area tends to mirror this pattern, with only minor local variation.
At RAC Esperance Holiday Park, river oak by the water is typically first out of the gate, climbing steadily from mid-winter into September. Grass pollen rises through spring toward a November high point, and remaining a significant allergen right through summer until it eases in February. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

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 Castletown 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. |
