Very Low Pollen in San Diego, CA

About pollen in San Diego

Pollen levels in San Diego are quiet today. Tree and grass pollen are both absent, while weeds are the only category showing any activity, and even that is at a very low level. Most people, including those with sensitivities, should notice little to no irritation outdoors right now. Looking ahead, this calm pattern is expected to hold steady over the next several days, with weed pollen remaining low and tree and grass staying negligible. This lines up with the seasonal calendar: local trees such as Jacaranda, Magnolia, and Podocarpus have long finished their spring release, and grasses are well past their early-summer peak. Weeds tend to linger into fall, so the mild presence being seen now fits the time of year, though conditions overall remain easy for most allergy sufferers to manage.
