Very Low Pollen in Baltimore, MD

About pollen in Baltimore

Pollen levels around Baltimore are quiet today. Tree pollen is essentially absent, and grass pollen is running very low, so most people should notice little to no irritation outdoors. If you tend to be highly sensitive, you might catch a faint trace of grass pollen, but conditions overall are about as calm as they get this time of year. Looking ahead, the next couple of days should bring more of the same, with grass pollen holding steady at a low level and tree pollen remaining out of the picture. This lull fits the season: the spring tree pollen surge from oaks and other area trees like ginkgo and magnolia has long since passed, and midsummer bloomers such as crape myrtle (Lagerstroemia) and smoketree (Cotinus) tend to contribute less to airborne pollen counts. With ragweed season still weeks away, this is a comparatively easy stretch for allergy sufferers in Baltimore.
