Local Environmental Conditions
This part of Silver Bay is surrounded mainly by woodland, which covers around 94% of the nearby area. Close to Penn Creek, riverside trees such as willow, poplar and alder add to local tree pollen. Alder, birch and maple are among the allergenic trees nearby. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
First to flower is alder, in mid-spring. Birch and maple follow in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in midsummer, with temperatures around 20°C, and their pollen lingers into late summer. Rain is heaviest in spring, often giving short breaks from high pollen levels. By late fall, pollen levels are low again.

Does pollen in Silver Bay 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 Silver Bay 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 Silver Bay, 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.
