Local Environmental Conditions
Residents in Fort William dealing with hay fever usually point to birch and pine as the culprits, particularly in spring near parks and gardens. Fields and hedgerows just outside town push grass pollen counts up noticeably once onshore breezes set in. Locals with allergies tend to plan around two peaks a year rather than one long stretch.
Ask anyone with allergies in Fort William and they'll tell you it's birch and pine that cause the trouble. Grass pollen then stretches from May into September, with the worst of it typically landing in June and July. Expect birch pollen roughly from March to May, before pine takes over, usually April to June. Something to plan around if pollen usually gets to you.

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. |
