About pollen in Las Cruces
Weed pollen is the main driver of today's conditions in Las Cruces, and levels are high enough to cause noticeable symptoms for anyone sensitive to it. Grass pollen is present but at only a trace level, while tree pollen is absent entirely, so weeds are really the only concern worth planning around today. Looking ahead, this pattern should hold steady through the next several days, with weed pollen staying high and grass remaining minimal. This fits the season well, as autumn in the desert Southwest is prime time for ragweed and other weeds to peak, even as grass pollen winds down and tree pollen stays dormant until species like mesquite, juniper, and cottonwood begin releasing again in spring. Anyone sensitive to weed pollen should expect little relief in the immediate forecast.
