About pollen in Fort Collins

Grass pollen is the main driver in Fort Collins today, sitting at a moderate level (3) and pushing the overall index to moderate as well. Tree pollen has dropped off to very low (1), which fits the calendar now that the spring surge from regional species like cottonwood, juniper, ash, and oak has faded. The five-day outlook holds steady, with grass staying at moderate and tree pollen remaining very low throughout. That flat trend is typical for late June, when grasses dominate the air during early summer. Weed pollen isn't being reported in the current data, though ragweed generally becomes a factor later in the season.
