About pollen in Livermore
Grass pollen is the main driver in Livermore today, sitting at a moderate level (3) and pushing the overall index to moderate as well. The forecast points to a modest easing ahead, with grass slipping from 3 today to 2 for the next four days. That fits the calendar, as grasses tend to dominate through late spring and into early summer once the spring tree-pollen surge has faded. Tree and weed levels aren't being reported in the current data, so grass remains the pollen to watch right now. Ragweed and other weeds typically pick up later in the summer and fall, so they're not a factor at this point in the season.
