About pollen in Joliet
Pollen levels in Joliet are quite calm today. Both tree and weed pollen are running very low, so most people should be able to spend time outdoors without much irritation. This is a quiet stretch overall, with no single pollen type standing out as a concern. Looking ahead, conditions should stay mild over the next couple of days before weed pollen begins to tick upward toward the end of the forecast period, moving into moderate territory. This lines up with the season, as late summer is when ragweed and other weeds typically become more active in the region, even as tree pollen from oaks, maples, and other local trees remains largely dormant until spring. Anyone particularly sensitive to weed pollen may want to keep an eye on the later part of the week as levels climb.
