Local Environmental Conditions
Hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen, a short distance from here. Oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two, in the vicinity. Here, in the surrounding area, a green space of mown lawn and planted trees, both feeding into local grass and ragweed counts.
Hazel and willow near the water open the pollen calendar early, reaching its high point sometime in late winter or early spring. As spring advances, oak and birch in the nearby woodland become the dominant source, building to its sharpest point across April and May. Grass pollen takes over next, building to a peak around June, before ragweed's late-summer surge carries the season into October.

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

Does pollen in Weston 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 Weston 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 Weston, 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. |
