Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels around Santa Monica are quiet today. Grass is the only real presence in the air, and even that is running very low, so most people should get through the day without any noticeable irritation. Tree pollen is essentially absent right now, giving allergy sufferers a welcome break on that front. Looking ahead, this calm pattern should hold steady over the next several days, with grass staying at a similarly low, easy-to-manage level. This lull is typical for midsummer in the area — the spring surge from trees like Prunus, Washingtonia, Eucalyptus, Plane, and Pine has long since passed, and grass pollen, which usually peaks earlier in the season, is now tapering off rather than ramping up. For now, conditions remain favorable for spending time outdoors with minimal pollen concern.
