Allergies & Pollen Count for Pine Ridge, South Dakota
Today's Condition
Discussion
The pollen levels for Monday will be falling and will remain in the extremely low range. This change results in part from falling temperatures, rising humidity and heavy rains in the morning, 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.
