Local Environmental Conditions
Around 86% of the area near this part of Sawyers Valley is woodland. 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. Grasses also feature strongly, alongside pigweed among the weeds.
Tree pollen comes first, peaking in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Sawyers Valley 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 Sawyers Valley 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 Sawyers Valley, 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.
