Low today, mostly weed pollen.
Last updated October 14, 2026
Weed pollen is the most active type in North Las Vegas today, though it remains at a low level overall. Most people should get through the day without much irritation, though those who are particularly sensitive to weed pollen may notice mild effects. Grass pollen is present as well, but at a very low level that is unlikely to cause issues, and tree pollen is absent entirely right now. Looking ahead, this pattern should hold steady over the next several days, with weed staying low and grass remaining minimal. Tree pollen is expected to stay quiet throughout, which fits the season, since local species like Mulberry, Elm, Honeylocust, Washingtonia, and Platycladus typically release their pollen in spring rather than fall. With autumn underway, weed pollen is the main contributor to watch, as this is its typical active stretch before cooler weather settles in later in the season.
