About pollen in Vista
Grass pollen is the only active driver in Vista today, sitting at a Low level of 2 on the Universal Pollen Index, which keeps the overall reading at Low as well. The forecast points to an easing trend, with grass slipping from 2 today to 1 for the remainder of the five-day window. Late June falls squarely in the grass season, which typically runs through late spring and early summer, so a modest grass presence is in line with expectations for this time of year. Tree pollen, which peaks earlier in spring, and weed pollen, which builds toward late summer with ragweed, are not reported in today's data. Overall, conditions are mild and trending lower in the days ahead.
