Local Environmental Conditions
The area around this part of Harrow is a mix of open grassland and woodland. Running water nearby means riverside vegetation is part of the local pollen picture. Woodland on all sides makes trees an important local pollen source. Grasses add a sizeable share of the local pollen. Roadside verges and patches of open ground provide further room for grasses and weeds.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Harrow 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 Harrow 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 Harrow, 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.
