Local Environmental Conditions
Local farmland and hedgerows nearby add meaningful grass pollen through late spring and summer, especially under cooler northerly winds. On top of that, oak and plane are the two species driving most tree pollen in Romford, especially around parks and green corridors. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.
Locals in Romford usually notice oak first, with plane not far behind it. 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. Worth factoring in if hay fever's ever been an issue for you here.

Does pollen in Romford 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 Romford 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 Romford, 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. |
