Local Environmental Conditions
Open water and built-up land share the area around this site in Williamstown. A nearby park adds mown lawns and planted trees to the local pollen mix. Oak is the most prominent allergenic tree nearby, with plane tree also present. Grasses are a major source, with pigweed and plantain adding to the weed pollen load.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak and plane tree are in full flower. Then come the grasses, strongest in early summer and fading by early fall. The season closes with pigweed and plantain from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.

Does pollen in Williamstown 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 Williamstown 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 Williamstown, 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.
