About pollen in San Diego

Pollen levels across San Diego are modest today, with both tree and grass categories sitting in the Low range and the overall index at 2 (Low). Grass is the type to keep an eye on, as late spring into early summer is its typical season, while lingering tree contributions from species like Jacaranda, Podocarpus, Cupaniopsis, Syagrus, and Syzygium remain limited. The grass forecast points to easing conditions, slipping from Low today to even lower readings over the next several days. With tree pollen past its spring peak and ragweed still well ahead of its late-summer window, overall exposure should stay light. Expect a quiet stretch for sensitive individuals heading into the coming days.
