Pollen Forecast for Portland, Texas

The pollen levels for Wednesday will be increasing but will still remain in the low range. Since the weather has a major influence on pollen dispersal, this increase is due in part to higher temperatures and windy conditions.

Concentration of pollen grains in the air for Thursday will be falling into the very low range. This relief in pollen levels is caused in part by rising humidity and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.
