Local Environmental Conditions
St Ives Cambridgeshire sees plane and lime as the leading tree pollen contributors, with levels differing noticeably between well-vegetated suburbs and the denser core. Surrounding Cambridgeshire farmland contributes substantial grass and tree pollen, moving into town when winds blow from the east. The relatively open, low-lying landscape lets pollen disperse readily across the area through the season.
In St Ives Cambridgeshire, the pollen calendar starts with plane and rolls straight into lime. Grass then takes over from May right through September, peaking around June and July for most people. Plane pollen typically runs from April to June, and lime keeps things going from May right through to July. Worth factoring in if hay fever's ever been an issue for you here.

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. |
