Local Environmental Conditions
Around New Malden, birch and lime are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Surrounding Kingston upon Thames farmland contributes substantial grass and tree pollen, moving into town when winds blow from the north-west. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.
The tree pollen story in New Malden is really about birch and lime, in that order. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Expect birch pollen roughly from March to May, then lime carries on from May until July. Worth keeping an eye on the forecast if you're sensitive.

Does pollen in New Malden come from nearby or far away?

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 New Malden 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 New Malden, 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. |
