Pollen Forecast for Sandy Spring, Maryland
High
Maple, Oak, Poplar/Aspen/Cottonwood
Discussion
The quantity of pollen grains in the air for Friday will be falling but will remain in the very high range. This change results in part from falling temperatures, lack of strong winds and expected precipitation in the evening which tends to wash pollen out of the air.
Allergy Facts
Some plants pollinate only in the evening or early morning hours. An example is a member of the particularly allergenic olive family, jasmine. Having this vine creeping by your open bedroom window at night may provide unwelcome night visits of pollen.
