Italian cypress
Cupressus sempervirens
Very low today, mostly weed pollen.
Last updated August 14, 2026
Pollen levels in Arden-Arcade are quiet today. Tree pollen is absent, and weeds are registering only a very low presence, so most people should get through the day without any noticeable irritation. Overall, this is about as calm as the air gets from an allergy standpoint. Looking ahead, the next several days should bring more of the same, with weed pollen holding steady at a low level and tree pollen remaining absent. This lull fits the season: local trees such as Plane, Oak, Ash, Robinia, and Sequoia typically shed their pollen back in spring, and grass season has also wound down. As late summer continues, keep an eye out for weeds like ragweed, which tend to become more active as autumn approaches.
