Local Environmental Conditions
Residents in Moretonhampstead dealing with hay fever usually point to birch and lime as the culprits, particularly in spring near parks and gardens. Grass pollen from surrounding Devon fields is significant through the summer months, carried in by light prevailing breezes. Hay fever sufferers here typically notice symptoms peaking in late spring, then again during the summer grass season.
For Moretonhampstead, the season kicks off with birch and then hands things over to lime. After that, grass pollen carries the season from May through to September, with June and July normally the toughest stretch. You'll usually see birch pollen from around March through May, while lime follows on from May to July. Good to know if you're planning anything outdoors that time of year.

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. |
