About pollen in Las Cruces
Weed pollen is the main concern in Las Cruces today, with levels running high enough to cause noticeable symptoms for those who are sensitive. Grass pollen is also present but at a low level, contributing only mildly to overall irritation. Tree pollen is absent, so anyone bothered by today's conditions is almost certainly reacting to weeds rather than trees or grass. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying high and grass remaining low and fairly consistent. This lines up with the season, as late September into fall is typically ragweed and other weed pollen's peak stretch in the region, while tree pollen stays quiet until the desert willows, mulberries, and other local trees begin releasing pollen again in spring. If you tend to react to ragweed, it's a good stretch to be mindful of outdoor exposure.
