Allergies & Pollen Count for Grand Forks, North Dakota
Today's Condition
Discussion
Pollen concentrations for Monday will be falling and will remain in the extremely low range. The cause for the falling pollen levels is rising humidity and heavy rains in the afternoon and evening which tend to wash pollen out of the air.
Allergy Facts
Most pollen grains are 20 to 40 micrometers in size, however, there are many that are far from the norm. Pumpkin pollen grains, for example, can reach 250 micrometers in diameter--almost large enough to see with the naked eye.
