About pollen in Redwood City
Grass pollen is the only type registering in Redwood City today, and it is sitting at a very low level. This means most people, even those who usually react to grass, should notice little to no irritation. Overall conditions are calm, making it a comfortable day to spend time outdoors without much concern about airborne allergens. Looking ahead, the next several days should bring more of the same, with grass pollen expected to hold steady at these low levels through the rest of the week. This lull fits the seasonal pattern for the Bay Area, where the main grass pollen surge typically comes earlier in late spring, and oaks, birches, and other regional trees have already finished their spring release. With summer underway, pollen activity is generally quieter until weeds like ragweed become more of a factor later in the season.
