Low Pollen in Boston, MA

About pollen in Boston

Grass pollen is the main story in Boston today, though levels are running low. Most people should be able to go about their outdoor plans without much trouble, though those with a strong grass sensitivity may notice mild effects. Tree pollen is essentially absent right now, so allergy sufferers can expect that source to stay quiet. Looking ahead, grass pollen is expected to hold at similarly low levels through the next several days, with only minor day-to-day shifts. This fits the seasonal pattern for early July, when the spring tree pollen from species like linden, honeylocust, maple, elm, and sophora has largely wound down, leaving grasses as the dominant allergen through summer. No major changes are expected in the near term, so conditions should remain manageable for most of the week.
