Local Environmental Conditions
In The Legend at Brandybrook, here, near this part of town, along the damp banks, hazel and willow release some of the year's first tree pollen. Here, in the wider area, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. The park's turf and planted trees form a small but steady source of grass and ragweed pollen, close by.
For The Legend at Brandybrook, further into spring, the area's oak and birch stands drive the pollen count, generally peaking somewhere between April and May. Moving into early summer, grass pollen climbs to its seasonal high in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

When is pollen season in Wales?
How often is the Wales pollen forecast updated?

Does pollen in Wales 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 Wales 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 Wales, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
