About pollen in Boise

Grass pollen is the main driver in Boise today, sitting at a moderate level and pushing the overall index to moderate as well. Tree pollen has dropped off to very low, which is typical now that the spring surge from trees like cottonwood, juniper, and ash has passed. The five-day forecast holds steady, with grass staying moderate and tree pollen remaining very low throughout, so expect more of the same in the days ahead. Late spring into early summer is the usual peak for grass pollen, matching what we're seeing right now. Weed pollen data isn't available in this coverage, so there's no reading to report there.
