High Pollen in Phoenix, AZ

About pollen in Phoenix

Weed pollen is the main driver of today's conditions in Phoenix, running high and likely noticeable for anyone with sensitivities. Grass is also active at a moderate level, adding to the mix, while tree pollen is quiet for now. Looking ahead, this pattern should hold steady through the next few days, with weed pollen actually ticking up to very high before easing slightly, and grass continuing at a moderate pace throughout. This lines up with the season — weeds, including ragweed, typically peak in the fall, while desert grasses can linger into this time of year as well. Tree pollen, which usually comes from species like mesquite, olive, and cottonwood in this region, stays dormant until spring, so it shouldn't factor into the picture for now.

What to do today

• Avoid mowing the lawn and raking leaves.
• 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).
