About pollen in Bloomington
Weed pollen is the main story in Bloomington today, sitting at a moderate level that may be noticeable if you tend to be sensitive. This is consistent with the season, as ragweed and related weeds are typically active into early fall, and moderate exposure can bring mild irritation for those prone to allergies, even if most people won't notice much difference in their day. Looking ahead, weed pollen is expected to climb to a high level over the next couple of days before dropping off sharply, becoming minimal and then essentially absent by the end of the five-day stretch. This pattern fits the tail end of the ragweed season in the region, which tends to wind down as temperatures cool. Tree pollen, which comes mainly from species like oak, maple, and hickory, is not a concern at this time of year, since it typically peaks in spring.
