Local Environmental Conditions
Residents in Shanklin dealing with hay fever usually point to plane and lime as the culprits, particularly in spring near parks and gardens. Surrounding Isle of Wight farmland contributes substantial grass and tree pollen, moving into town when winds blow from the north. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.
Pollen season in Shanklin really gets going with plane, followed not long after by lime. Grass season overlaps a lot of this too, running May through September and peaking mid-summer. Plane pollen typically runs from April to June, then lime carries on from May until July. Handy to bear in mind before booking that garden party.

How often is the Shanklin pollen forecast updated?

Does pollen in Shanklin 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 Shanklin 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 Shanklin, 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. |
