Cupressus sempervirens
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in Santa Clara are quiet today. Tree pollen is absent, and grass pollen is registering at a very low level, so most people should notice little to no irritation outdoors. Even those with sensitivities are unlikely to feel much effect under these conditions. Looking ahead, grass pollen is expected to hold steady at this same low level over the next couple of days, with no significant change on the horizon. This lines up with the typical seasonal pattern: tree pollen from species like Pistacia, Liquidambar, Ginkgo, Syagrus, and Maple has already wound down after peaking earlier in the year, and grass pollen, while still present, is easing as summer progresses. For now, conditions remain mild and easy to manage.
