Local Environmental Conditions
Grass pollen from surrounding South Lanarkshire fields is significant through the summer months, carried in by moist Atlantic fronts. On top of that, Scots pine and birch are the two species driving most tree pollen in Hamilton, especially around parks and green corridors. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.
So here's the rundown for Hamilton: scots pine pollen shows up first, then birch takes over. Scots pine tends to release pollen between April and June, before birch takes over, usually March to May. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Not a bad idea to stock up on antihistamines before it all kicks off.

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