Local Environmental Conditions
The area around this location in Security-Widefield is mostly open grassland, with a good deal of built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. Grass pollen adds noticeably to the overall load. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Grasses take over in early summer and keep pollen in the air into late summer. A smaller weed peak follows from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around freezing, pollen levels are low again.

Are pollen levels in Security-Widefield 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 Security-Widefield, 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.
