Local Environmental Conditions
Around 46% of the area near the heart of Bishops Waltham is woodland, with a good deal of open grassland and some built-up land. Hazel, oak and maple are among the allergenic trees nearby. Grasses and weeds such as plantain round out the local mix. Roadside verges and patches of open ground provide further room for grasses and weeds.
The pollen year starts in late winter, when hazel flowers. Oak and maple follow in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in early summer and easing off by late summer. The season closes with plantain from late spring into late summer. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Bishops Waltham pollen forecast updated?

Does pollen in Bishops Waltham come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. 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 Bishops Waltham based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Bishops Waltham, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
