Local Environmental Conditions
Around 39% of the area near this site in Otsego is open grassland, with a good deal of farmland and some woodland. Trees are an important local pollen source, given how much woodland surrounds the area. There is plenty of grass pollen here too. Pasture and uncultivated field edges in the farmland provide room for grasses and weeds.
Tree pollen comes first, peaking in mid-spring. Grass pollen follows, peaking in early summer and easing off 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 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 Otsego 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 Otsego, 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.
