Local Environmental Conditions
Hay fever sufferers here typically notice symptoms peaking in late spring, then again during the summer grass season. That's on top of alder and birch, which are the main local tree pollen sources around Redcar Coatham's parks and quieter streets. Surrounding Redcar and Cleveland farmland contributes substantial grass and tree pollen, moving into town when winds blow from the the coast.

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. |
