About pollen in San Pedro

Pollen levels in San Pedro are quite mild today. Grass is the only pollen type showing any activity, and even that is at a very low level, so most people should not notice any effects. Tree pollen is absent entirely, keeping overall conditions calm for anyone sensitive to seasonal allergens. Looking ahead, grass pollen is expected to hold steady at this same low level over the next several days, with no signs of a meaningful increase. This fits the seasonal pattern for midsummer, as trees like Pittosporum, Ash, Pine, Araucaria, and Washingtonia have largely finished their pollen release for the year. With tree pollen quiet and grass staying subdued, conditions should remain comfortable for those who typically deal with allergy symptoms this time of year.
