High Pollen in Peoria, IL

About pollen in Peoria

Weed pollen is the main driver of today's conditions in Peoria, and it is running high. This is the kind of level that tends to be noticeable even for people who don't usually think of themselves as sensitive, and those with known weed allergies should expect a fairly bothersome day, particularly with outdoor activity in the afternoon. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing to a more moderate level, then bouncing between lighter and moderate readings through the rest of the week. This pattern fits the season: late September is peak time for ragweed, the region's dominant fall weed allergen, and levels typically stay elevated until the first hard frost knocks the season back. Tree pollen from species like oak and maple is dormant this time of year and won't return until spring, so weeds remain the one to watch for now.

What to do today

• When driving the car, close your windows and turn the air conditioning system to recirculation mode.
• Keep your windows closed and turn on your air purifier or air conditioning.
• Consider staying indoors during the peak pollen hours (morning and early afternoon).
