Italian cypress
Cupressus sempervirens
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in Arden-Arcade remain quiet today. Grass is the only type showing any activity, and even that is at a very low level, unlikely to cause much trouble for most people. Tree pollen is absent entirely, so those sensitive to species like alder, oak, or mulberry should get a break for now. Looking ahead, the next several days should bring more of the same, with grass holding steady at a low level and tree pollen staying quiet throughout. This lull is typical for midsummer, since the local trees—including alder, malus, mulberry, pyrus, and oak—finished their main pollen release back in spring. With grass season easing and ragweed not yet in play, this is generally a calmer stretch for allergy sufferers in the area.
