About pollen in San Bernardino
Weed pollen is the main concern in San Bernardino today, sitting at a moderate level that may be noticeable if you tend to be sensitive. Grass pollen is present but at a very low level, unlikely to cause much trouble, and tree pollen is essentially absent right now. Looking ahead, this pattern should hold steady over the next several days, with weed pollen remaining moderate and grass staying very low. Tree pollen is expected to stay quiet, which fits the season, since local trees like oak and sycamore typically release their pollen in spring rather than fall. This time of year is more about weeds such as ragweed, which tend to peak in late summer and into autumn, so it makes sense that they are the more active pollen type right now.

- Wash clothes worn outdoors to remove any remnants of pollen grains.
