Coldstream's parks and green spaces feature Scots pine and birch as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. Fields and hedgerows just outside town push grass pollen counts up noticeably once the prevailing Atlantic airflow set in. The relatively open, low-lying landscape lets pollen disperse readily across the area through the season.

Scots pine pollen typically runs from April to June, and birch keeps things going from March right through to May. Handy to bear in mind before booking that garden party.
How often is the Coldstream pollen forecast updated?

Does pollen in Coldstream 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 Coldstream 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 Coldstream, 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.
