Local Environmental Conditions
The area around the center of Addiscombe is a mix of built-up land and woodland, plus some open grassland. Common allergenic trees nearby include oak, maple and hazel. Grasses and weeds such as plantain and mugwort round out the local mix. Locally, planted trees and mown lawns are the main sources in the built-up parts.
Hazel opens the pollen season in late winter. Oak and maple follow in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by late summer. Plantain and mugwort bring a final peak from late spring into late summer. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

Does pollen in Addiscombe 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 Addiscombe 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 Addiscombe, 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.
