About pollen in Vallejo

Grass pollen is the main player in Vallejo today, registering Low at level 2 on the Universal Pollen Index, with the overall reading also sitting at Low. Tree and weed pollen come with no data, so grass is what's worth watching right now. The five-day forecast holds grass steady at level 2 throughout, so expect more of the same with no notable spikes or drops ahead. This tracks with the season: late June falls within the typical late-spring-into-summer window when grasses tend to dominate, while spring's tree pollen has largely faded and ragweed season is still months off in late summer and fall.
