Moderate today, mostly tree pollen.
Last updated October 14, 2026
Tree pollen is the main story in Elk Grove today, registering at a moderate level that could be noticeable for those who tend to react to it. Grass pollen remains very low, and weed pollen is holding at a mild level, so neither should cause much trouble. Overall, it is a fairly manageable day, with tree pollen as the one category worth keeping in mind if you are especially sensitive. Looking ahead, weed pollen is expected to stay low through the next several days before easing slightly toward the end of that stretch, while grass pollen should remain minimal throughout. Tree pollen at a moderate level is a bit unusual for mid-October, since trees like oak, maple, plane, zelkova, and nyssa typically release most of their pollen in spring. This autumn uptick is likely tied to local conditions rather than a seasonal surge, so it is worth watching but not something that is expected to intensify in the way spring tree pollen does.
