About pollen in South Boston

Tree pollen is the only type registering in South Boston today, and it remains at a low level. Most people should be able to go about their day without much irritation, though those with a strong sensitivity to tree pollen may still notice mild effects, particularly with familiar local sources like oak, maple, and elm still present in the air this time of year. Looking ahead, tree pollen is expected to stay low or ease slightly over the next several days, staying gentle through the week. This tracks with the season, as the heavier tree pollen releases of spring are well behind us, and the more typical summer allergy trigger, grass, along with ragweed later in the season, tends to take over as the main source of irritation. For now, conditions look calm and manageable.
