Local Environmental Conditions
Nottingham's parks and green spaces feature sycamore and oak as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. The nearby patchwork of fields adds further grass and tree pollen exposure, particularly under onshore breezes. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.
If you're wondering when hay fever kicks off in Nottingham, it's mostly down to sycamore and oak. Grass then takes over from May right through September, peaking around June and July for most people. Expect sycamore pollen roughly from April to June, before oak takes over, usually April to May. Worth keeping an eye on the forecast if you're sensitive.

How often is the Nottingham pollen forecast updated?

Does pollen in Nottingham 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 Nottingham 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 Nottingham, 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. |
