Velvet ash
Fraxinus velutina
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in Spring Valley are quiet today. Grass is the only pollen showing any activity, and even that is at a very low level, meaning most people should be able to go about their day without much irritation. Tree pollen is essentially absent right now, so those sensitive to species like Celtis, ash, eucalyptus, oak, or rhus should get a break from that particular trigger. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass staying at a mild, low level and no meaningful tree pollen in the mix. This lines up with the season, since local trees typically release their heaviest pollen in spring and have largely wound down by midsummer. With grass now the main source of any activity, sensitive individuals may notice mild effects on drier, breezier days, but overall conditions remain comfortable for this time of year.
