About pollen in Vista
Pollen activity in Vista is quiet today. Both grass and weed pollen are running very low, and most people should move through the day without any irritation. Even those who are usually sensitive to these pollen types are unlikely to notice much of an effect. Looking ahead, the next several days should bring more of the same, with grass and weed levels holding steady at very low readings through the week. This fits the season well, since early October is past the peak for grasses and still ahead of the stronger weed pollen stretch that typically builds later in fall. Tree pollen from species like oak and sycamore, which are more active in spring, isn't a factor right now, so overall conditions remain mild and easy to manage.
