Spring is finally here meaning pleasant weather, sunnier days, and unfortunately more pollen. In the Rockville MD area, pollen season can start as early as February and can extend all the way until June. The current season has been relatively mild so far, mostly because of colder and rainy weather in March but when the area gets a string of sunny days that’s when pollen counts could explode. Early April counts for pollen were close to normal this year, averaging around 318 grains per cubic meter. Counts are predicted to surge into the 2000 grains per cubic meter range in early May based on data from previous years.
The biggest pollen offenders in Rockville come from oak, pine, and grass. Pollen coming from pine trees can be especially irritating because it is usually bigger compared to other tree pollens. Grass pollen on the other hand, is practically invisible to the human eye because it is microscopic. Uncut grass releases the most pollen since the plant needs to reach a certain hight in order to effectively release pollen. Grass pollen is usually more prevalent later in the allergy season, around mid to late spring.
