Local Environmental Conditions
Most of the area around the heart of Big Rock Township is farmland, with some woodland and open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Grass pollen adds noticeably to the overall load. Pasture and uncultivated field edges in the farmland provide room for grasses and weeds.
Flowering trees bring the first pollen of the year in mid-spring. Then come the grasses, strongest in early summer and fading 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 5°C, pollen levels are low again.

Are pollen levels in Big Rock Township 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 Big Rock Township, 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.
