Local Environmental Conditions
Almost 50% of the area near this site in Central Elgin is open water, with some woodland and built-up land. Along a stream or river nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Grasses growing in the surroundings are the main non-tree source of pollen.
Flowering trees bring the first pollen of the year in late 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. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

Does pollen in Central Elgin 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 Central Elgin 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 Central Elgin, 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.
