Fraxinus velutina
Low today, mostly grass pollen.
Last updated September 29, 2026
Grass and weed pollen are both running at low levels in North Las Vegas today, while tree pollen is absent. Most people should be able to go about their day without much irritation, though those who are particularly sensitive to grasses or weeds may notice mild symptoms, especially with time spent outdoors. Looking ahead, conditions are expected to hold steady over the next several days, with grass and weed pollen remaining at low levels and tree pollen staying quiet. This pattern fits the season well: local trees such as Mulberry, Elm, Honeylocust, Washingtonia, and Platycladus have their peak activity in spring, so it's normal for tree pollen to be inactive this time of year. Meanwhile, weed pollen, including ragweed, tends to linger into early fall, which explains its continued low but steady presence.
