Velvet ash
Fraxinus velutina
Very low today, mostly grass pollen.
Last updated August 15, 2026
Pollen activity around Las Vegas remains minimal today. Tree pollen is absent altogether, while both grass and weed are present only at very low levels. Most people, including those with sensitivities, should notice little to no irritation from pollen under these conditions. Looking ahead, the next several days should bring more of the same, with grass and weed holding steady at low levels and tree pollen staying quiet. This lull fits the season, as the desert's tree bloom from species like ash, pistacia, and the various palms — Washingtonia, Chamaerops, and Phoenix — wrapped up months ago, while late-summer weed pollen has yet to build toward its typical autumn rise. For now, conditions remain calm and easy on most allergy sufferers.
