About pollen in San Diego

Pollen levels around San Diego are quiet today. Tree pollen is absent, and weeds are contributing only a very light presence in the air. Overall, this is a low-impact day for most people, including those who usually notice seasonal pollen. Looking ahead, this calm pattern is expected to hold over the next several days, with weed pollen staying at a similarly low level and tree pollen remaining out of the picture. This fits the season well: local trees such as Cupaniopsis, Jacaranda, Magnolia, Podocarpus, and Syagrus typically release most of their pollen earlier in the year, so their absence now is expected. With grass season winding down and the peak of weed pollen, including ragweed, still ahead in the coming weeks, conditions should stay comfortable for now.
