Low Pollen in Las Vegas, NV

About pollen in Las Vegas

Weed pollen is the main source of activity in Las Vegas today, though it remains at a low level that most people won't notice. Grass is present but only in trace amounts, and tree pollen is absent entirely. Overall, this is an easy day for allergy sufferers, with little in the air to cause discomfort. Looking ahead, conditions are expected to hold steady through the next several days, with weed pollen staying low and grass continuing at very low levels. Tree pollen should remain quiet, which fits the season — local trees like ash, pistache, and the various palms typically release their pollen in spring, not fall. The mild weed presence is more typical for this time of year, as some weeds continue to linger into autumn before tapering off with cooler weather.
