Local Environmental Conditions
The center of Surrey is surrounded mainly by built-up land, with a good deal of woodland. With the Fraser River nearby, riverside trees such as poplar and alder along its banks contribute to the local mix. Maple heads the list of allergenic trees nearby, ahead of alder. Grasses also feature strongly, alongside plantain among the weeds.
The pollen year starts in early spring, when alder flowers. Maple follows in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in midsummer and fading by late summer. Later, plantain keeps weed pollen in the air from late spring into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

How often is the Surrey pollen forecast updated?
The Surrey pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Surrey 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 Surrey 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 Surrey, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
