Summerville's Dorchester County South Carolina Charleston suburban setting features longleaf pine, live oak, and sweetgum as the main tree pollen sources, with exposure varying between the wooded Sawmill Branch and Four Mile Branch corridor residential areas and the more built-up commercial corridors along US 17A. The Ashley River corridor to the west provides locally significant green space, while the surrounding South Carolina Lowcountry pine-oak woodland contributes substantial regional tree pollen throughout the spring season.

Does pollen in Summerville 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 Summerville 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 Summerville, 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.
