Local Environmental Conditions
This location in Brazoria is surrounded mainly by woodland, with a good deal of open grassland. With a watercourse close by, riverside vegetation contributes to the local mix. Allergenic trees nearby include oak. Grass pollen is a substantial part of the local mix as well. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Tree pollen comes first, with oak in flower from early spring into mid-spring. Grass pollen follows, highest around late spring and gone by late summer. Weeds take the season into its final stretch, adding modest amounts of pollen from early summer into early fall. Locally, temperatures range from around 10°C in the coldest month to around 30°C in the warmest, with rain spread fairly evenly through the year.

Does pollen in Brazoria 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 Brazoria 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 Brazoria, 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.
