Local Environmental Conditions
Built-up land makes up around 44% of the area near this part of Orland Hills, with a good deal of woodland and some open grassland. With running water close by, riverside vegetation contributes to the local mix. Common allergenic trees nearby include oak. Grass pollen is a substantial part of the local mix as well.
Oak leads the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. A smaller weed peak follows from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Orland Hills 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 Orland Hills 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 Orland Hills, 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.
