Mount Pleasant's pollen season in South Carolina opens with oak and pine from late January, producing intense tree pollen through February and March. Grass pollen follows through April and May, with ragweed extending the season into October. The Charleston Harbour position means coastal breezes can periodically disperse pollen, while surrounding South Carolina coastal plain woodland and wetlands contribute substantial tree and grass pollen throughout the extended season.

The Mount Pleasant pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Mount Pleasant, 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.
