Local Environmental Conditions
Around Loftus, birch and oak are the dominant species behind local tree pollen, with counts higher near parks than in the centre. The wider North Yorkshire countryside supplies additional tree and grass pollen, particularly when shifting coastal winds carry it toward the built-up area. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.
Pollen season in Loftus really gets going with birch, followed not long after by oak. Birch gets going around March and tapers off by May, with oak picking up between April and May. Then grass pollen takes the baton from May all the way to September, usually peaking in June and July — that's when most people really feel it. Worth keeping an eye on the forecast if you're sensitive.

How often is the Loftus pollen forecast updated?

Does pollen in Loftus 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 Loftus 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 Loftus, 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. |
