About pollen in Las Vegas

Grass and weed pollen are both running low around Las Vegas today, while tree pollen is absent entirely. Most people should get through the day without much irritation, though anyone with a strong sensitivity to grasses or weeds may notice mild symptoms, particularly outdoors during the warmer afternoon hours. Looking ahead, this pattern is expected to hold steady over the next several days, with grass and weed levels staying low and tree pollen remaining quiet. This lines up with the seasonal shift into fall, when local trees such as ash, pistacia, and the various palms typically go dormant, while lingering weed pollen tends to be the main source of any outdoor irritation this time of year.
