Local Environmental Conditions
The area around Little Falls is a mix of built-up land and woodland, plus some open water. Along running water nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Woodland on all sides makes trees an important local pollen source. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around freezing, pollen levels are low again.

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 Little Falls 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 Little Falls, 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.
