Local Environmental Conditions
The relatively open, low-lying landscape lets pollen disperse readily across the area through the season. That's on top of rowan and alder, which are the main local tree pollen sources around Haddington's parks and quieter streets. Surrounding East Lothian farmland contributes substantial grass and tree pollen, moving into town when winds blow from the north-west.
In Haddington, the pollen calendar starts with rowan and rolls straight into alder. Grass season overlaps a lot of this too, running May through September and peaking mid-summer. Rowan gets going around May and tapers off by June, before alder takes over, usually January to April. Something to plan around if pollen usually gets to you.

When is pollen season in Haddington?
How often is the Haddington pollen forecast updated?
The Haddington pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Haddington 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 Haddington 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 Haddington, 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. |
