About pollen in Chino

Grass pollen is the main player in Chino today, registering at a low level on the index, while overall pollen also sits at low. Tree pollen has dropped to none, which is typical as the spring tree season winds down and gives way to grasses. Looking ahead, the five-day grass forecast holds steady at the same low reading, so don't expect any significant swings in the coming days. This pattern fits the calendar, with grass pollen tending to dominate through late spring and into early summer. Weed pollen, including ragweed, has no data reported here, though that category generally becomes more relevant later in the summer and fall.
