About pollen in Fremont

Grass pollen is the main driver in Fremont today, sitting at a Low level (2 on the index) and setting the overall reading at the same Low mark. The five-day outlook holds steady, with grass forecast to stay at 2 each day, so expect no meaningful change in the near term. Late June falls within the typical late-spring-to-early-summer window when grasses are the dominant source, while tree pollen has generally faded from its spring peak. No tree or weed data is available for the city right now, so today's picture rests on the grass readings alone. Ragweed and other weeds tend to ramp up later in summer and into fall, but there's nothing in the current numbers to point to that yet.
