Pollen Forecast for Oswego, Illinois

Today

The quantity of pollen grains in the air for Friday will be greater than today's levels in the high range. This rise is a result of rising temperatures, strong winds and lower relative humidity. If you have these allergies, tomorrow will likely be more difficult outdoors.

Outlook

Concentration of pollen grains in the air for Saturday will be falling in the low range. This forecast of lower pollen concentration is based on rising humidity, weakening winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. That's good news for allergy sufferers.
