Canary island pine
Pinus canariensis
Very low today, mostly grass pollen.
Last updated September 30, 2026
Pollen activity in Santa Ana is quiet today. Tree pollen is absent, while grass and weed pollen are both at very low levels, which means most people should not notice any effect. Even those with sensitivities are unlikely to feel much irritation under these conditions. Looking ahead, the pattern should hold steady over the next several days, with tree pollen staying absent and grass and weed levels remaining low but present. This fits the season well: local trees like oak, elm, callistemon, pittosporum, and lophostemon typically release their heaviest pollen in spring, so their dormancy now is expected. Weeds such as ragweed are more common in late summer and early fall, but their presence here remains minimal, so overall conditions should stay easy to manage in the near term.
