Platanus acerifolia
Very low today, mostly weed pollen.
Last updated August 14, 2026
Pollen counts around Berkeley are quiet today. Tree pollen is essentially absent, and weeds are only registering a very low presence, so most people should be able to go about outdoor plans without much concern. Even those with sensitive noses are unlikely to notice much in the air right now. Looking ahead, this calm pattern is expected to hold over the next several days, with weed pollen staying at a low, steady level and tree pollen remaining minimal. This tracks with the season: local trees such as ash, liquidambar, tristaniopsis, pittosporum, and prunus finished their main pollen release back in spring, and grass has largely wound down as well. With late summer underway, weeds are the main contributor to the pollen picture, though at these low levels they are not expected to cause much trouble in the near term.
