Canary island pine
Pinus canariensis
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels around Garden Grove remain quiet today. Tree pollen is essentially absent, and grass pollen is running very low, 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 these low levels over the next several days, offering a stretch of easy conditions for anyone prone to seasonal reactions. This lull fits the pattern for midsummer, as the region's trees—including elm, liquidambar, cupaniopsis, podocarpus, and syagrus—have largely finished their spring release and are contributing little to the air right now. With grass pollen typically lingering into early summer, it's worth keeping an eye on any modest upticks, but for now, outdoor plans should be largely unaffected by pollen.
