About pollen in Tustin
Pollen levels in Tustin are quiet today, with both grass and weeds registering at the low end of the scale. Most people should be able to go about their outdoor plans without much irritation, and those with sensitivities are unlikely to notice much of a reaction. Looking ahead, conditions are expected to hold steady over the next several days, with grass and weed pollen staying at similarly low levels. This tracks with the season, as autumn in Southern California tends to bring a lull between late-summer weed pollen, including ragweed, and the tree pollen that typically ramps up in late winter and spring from species like oak, sycamore, and olive. For now, there is little reason to expect pollen to be a significant concern in the area.
