Like the rest of Baltimore, Locust Point experiences a season that opens with cedar and elm from late February with oak following close behind through April. Grass pollen builds through May and June, and mugwort and nettle extend exposure into September. Relatively mild winters here bring the tree pollen season forward compared to points further north, which shapes conditions at Locust Point much as it does elsewhere in Baltimore.

The Baltimore 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 Baltimore, 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.
