About pollen in Vallejo
Pollen levels around Vallejo are quiet today, with grass the only type registering any activity, and even that is running very low. Most people should be able to spend time outdoors without much irritation, and those with sensitivities are unlikely to notice more than a mild effect, if any. Looking ahead, grass pollen is expected to hold steady at this same low level through the next several days, so no significant changes are on the horizon. This lull fits the season reasonably well: the region's oaks and other spring-blooming trees have already finished their peak pollen production, and grass, which typically runs from late spring into summer, appears to be tapering off rather than surging. Ragweed and other late-summer weeds have not yet become a factor this time of year.
