Low Pollen in Baltimore, MD

About pollen in Baltimore

Tree pollen is the main driver in Baltimore today, sitting at a moderate level and pushing the overall index to moderate as well. Lingering contributors among the local species can include plane, oak, maple, zelkova, and Cupressocyparis, though tree counts have generally eased well past their spring peak. Grass pollen is running low for now, and the five-day outlook holds it steady at that low level throughout. With it being late June, grass is the more seasonally relevant source heading into early summer, while ragweed and other weeds are still some weeks off. Forecast data for tree and weed pollen isn't available, so expect grass to remain the category to watch in the coming days.
