About pollen in San Bernardino
Weed pollen is the only real presence in San Bernardino today, and it remains at a low level. Most people should get through the day without much irritation, though those who are especially sensitive to weed pollen may notice mild symptoms, particularly during outdoor activity in the afternoon. Looking ahead, weed pollen is expected to hold steady at this same low level over the next several days, so no significant changes are on the horizon. This lines up with the seasonal pattern for the region: tree pollen from species like oak and sycamore typically peaks back in spring, grasses build through late spring into early summer, and weeds—especially ragweed—tend to become more prominent as late summer turns to fall. Right now conditions sit in a relatively quiet stretch before that seasonal weed uptick fully takes hold.
