Canary island pine
Pinus canariensis
Very low today, mostly tree pollen.
Last updated July 28, 2026
Pollen levels across Garden Grove remain quiet today. Tree pollen is the only category showing any activity, and even that is running very low, so most people should notice little to no effect. Those with sensitivities to trees like pine, plane, or the native palms and ficus common in the area are unlikely to feel much discomfort under these conditions. Looking ahead, tree pollen is expected to stay at this same low level through the next several days, with no signs of a notable rise on the horizon. This lull fits the season well, since summer in Southern California typically brings a natural dip in tree pollen after the spring peak, while grass activity has largely wound down and ragweed season has not yet begun. For now, conditions look favorable for anyone who tends to react to airborne pollen.
