About pollen in Sioux City
Weed pollen is the main contributor to today's conditions in Sioux City, sitting at a moderate level. Ragweed is the likely source this time of year, and those who are sensitive to it may notice some mild symptoms, especially during outdoor activity in the afternoon. For most people, though, the impact should stay manageable. Looking ahead, weed pollen is expected to hold steady over the next few days before easing slightly toward the end of the five-day stretch. This tracks with the typical fall pattern, as ragweed continues to linger into early October before cooler temperatures and the first hard frosts bring the season to a close. Tree pollen, which comes from species like oak, maple, and elm, remains dormant this time of year and won't become a factor again until spring.
