Low today, mostly weed pollen.
Last updated October 9, 2026
Weed pollen is the most active category in Van Nuys today, though it remains at a low level that most people will not notice. Grass pollen is present but very low, and trees are quiet for the moment. Overall, this is an easy day for allergy sufferers, with only mild potential for irritation if you are especially sensitive to weeds. Looking ahead, conditions are expected to hold steady through the next several days, with weed pollen easing slightly and grass staying at a consistently low level. Tree pollen should remain absent for now, which fits the season, since local species like ficus, ash, melia, carob, and queen palm typically release their pollen in spring rather than fall. This time of year in the San Fernando Valley is more closely tied to weed pollen, which tends to linger into early autumn before tapering off as cooler weather sets in.
