Very low today, mostly weed pollen.
Last updated August 14, 2026
Pollen activity in Alhambra is quiet today. Tree pollen is absent, and weeds are running at only a very low level, so most people should notice little to nothing in the way of symptoms. Overall, this is a calm day for allergy sufferers across the area. Looking ahead, weed pollen is expected to inch up slightly over the next several days, moving from very low toward a more moderate presence that sensitive individuals may start to notice. Tree pollen should stay quiet, which fits the season: local trees like plane, oak, elm, and ceratonia typically release their pollen earlier in the year and are largely finished for now. Late summer is more often a time for weed pollen to build gradually, so it is worth keeping an eye on that trend in the coming days.
