About pollen in Tustin

Pollen levels in Tustin remain quiet today, with weeds standing as the only category showing any real activity, and even that is running very low. Most people should be able to go about their outdoor plans without much concern, and those with sensitivities are unlikely to notice more than a faint effect, if anything at all. Looking ahead, the next several days should bring more of the same, with weed pollen staying at a low level throughout the stretch. This lull fits the season: local trees such as eucalyptus, oak, and sycamore already had their peak months back in spring, and grasses eased off after early summer. Late summer is typically when ragweed and other weeds start to stir in Southern California, so it's worth keeping an eye out as the season progresses, even though conditions are calm for now.
