Canary island pine
Pinus canariensis
Very low today, mostly tree pollen.
Last updated September 29, 2026
Pollen levels across the board are low in Garden Grove today. Tree, grass, and weed pollen are all barely registering, so most people should be able to go about outdoor activities without much irritation. Even those with sensitivities are unlikely to notice much of a difference right now. Looking ahead, this quiet stretch is expected to continue through the next several days. Tree pollen, already minimal from local species like pine, plane, and cupaniopsis, is expected to fade further and settle near zero. Grass and weed pollen should hold steady at low levels rather than climb. This lull fits the season, as early fall tends to sit between summer grass activity and the milder tree pollen production of cooler months, giving allergy sufferers a bit of a breather before conditions shift again later in the year.
