Local Environmental Conditions
Hoo Peninsula sees oak and plane as the leading tree pollen contributors, with levels differing noticeably between well-vegetated suburbs and the denser core. Fields and hedgerows just outside town push grass pollen counts up noticeably once light prevailing breezes set in. This mix of urban and rural influence gives Hoo Peninsula a fairly typical pollen pattern for the wider region.
So here's the rundown for Hoo Peninsula: oak pollen shows up first, then plane takes over. Oak gets going around April and tapers off by May, and plane keeps things going from April right through to June. Grass then takes over from May right through September, peaking around June and July for most people. Handy to bear in mind before booking that garden party.

Does pollen in Hoo Peninsula come from nearby or far away?

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 Hoo Peninsula 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 Hoo Peninsula, 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 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. |
