High Pollen in Fort Collins, CO

About pollen in Fort Collins

Weed pollen is the main story in Fort Collins today, sitting at a moderate level that sensitive individuals will likely notice. Tree pollen is quiet, so any late-summer irritation is almost certainly coming from weeds rather than trees. Looking ahead, weed pollen is set to climb over the next several days, moving from moderate into high and eventually very high territory by the end of the forecast window. This tracks with the seasonal pattern for mid-August, when ragweed and other late-summer weeds typically intensify their pollen release across the Front Range. Tree pollen, having finished its spring push from species like cottonwood and elm, should remain absent through this period, leaving weeds as the dominant allergen to watch in the days ahead.

What to do today

• When driving the car, close your windows and turn the air conditioning system to recirculation mode.
• Keep your windows closed and turn on your air purifier or air conditioning.
• Consider staying indoors during the peak pollen hours (morning and early afternoon).
