About pollen in Tustin
Grass pollen is the main player in Tustin today, sitting at a Low level (2 on the Universal Pollen Index), and it's the only category currently reporting data. The overall index also reads Low at 2, so conditions are fairly mild across the board. The five-day outlook holds steady, with grass staying at 2 each day and no upward or downward swing expected. This is consistent with the season, as grass pollen tends to be most active in late spring and early summer. Tree pollen, which typically peaks earlier in spring, isn't being measured right now, and ragweed generally doesn't ramp up until later in summer and fall.
