About pollen in Redwood City

Grass pollen is the main player in Redwood City today, sitting at a Low level (2 on the index), which matches the overall Low reading. Tree and weed pollen aren't being reported right now, so grass is effectively driving conditions. The five-day forecast holds steady, with grass staying at a 2 throughout, so don't expect much change in the days ahead. This tracks with the season, as grass pollen typically peaks in late spring and early summer, while the heavier tree pollen of spring has eased and ragweed season is still months off. All told, a calm and stable stretch for sensitive residents.
