Seaport District sees the same pollen timeline as the rest of Boston, beginning with maple and elm in March before birch and oak takes over and peaks through April and May. Grass pollen then peaks through June and July, and a modest weed pollen tail continues into September. The New England climate compresses tree, grass, and weed pollen into a shorter but intense season, a pattern felt across this part of Boston.

The Boston 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 Boston, 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.
