Local Environmental Conditions
The area around the center of Milford Haven is a mix of built-up land and open water, plus some woodland. Woodland on all sides makes trees an important local pollen source. Beyond the trees, grasses matter a great deal, and plantain is the main weed source. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Flowering trees bring the first pollen of the year in mid-spring. Grass pollen follows, peaking in midsummer and easing off by early fall. The season closes with plantain from late spring into late summer. Warm, damp weather from midsummer into early fall also raises mold spore levels. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

Does pollen in Milford Haven 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 Milford Haven 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 Milford Haven, 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.
