Local Environmental Conditions
Around Canary Wharf, plane and lime are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Surrounding London, City of farmland contributes substantial grass and tree pollen, moving into town when winds blow from the south-west. Hay fever sufferers here typically notice symptoms peaking in late spring, then again during the summer grass season.
So here's the rundown for Canary Wharf: plane pollen shows up first, then lime takes over. Expect plane pollen roughly from April to June, and lime keeps things going from May right through to July. After that, grass pollen carries the season from May through to September, with June and July normally the toughest stretch. Not a bad idea to stock up on antihistamines before it all kicks off.

How often is the London pollen forecast updated?

Does pollen in London 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 London 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 London, 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. |
