About pollen in Chino

Weed pollen is the only real presence in Chino's air today, and it remains at a low level, meaning most people should get through the day without much irritation. Tree pollen is absent right now, so overall conditions stay mild and manageable for the majority of residents, including those with mild sensitivities. Looking ahead, weed pollen is expected to hold steady at this same low level through the next several days, with no significant swings in either direction. Tree pollen should stay quiet as well, which lines up with the season, since local trees such as oak, sycamore, and olive typically finish their pollen release well before late summer. This time of year in Southern California is more commonly associated with weed pollen, including species that tend to linger into the fall, so the current pattern is fairly typical for mid-August.
