About pollen in Tustin
Grass pollen is the only type registering in Tustin today, and it remains at a very low level. Most people, including those with sensitivities, should notice little to no irritation from pollen today, making it a comfortable day to spend time outdoors. Looking ahead, grass pollen is expected to hold steady at this same low level through the next several days, so no significant change is on the horizon. This is a typical lull for midsummer in the region, as the main grass pollen surge usually comes earlier in the season, and local trees such as oak, sycamore, and eucalyptus are past their peak release for the year. If conditions shift or ragweed activity begins to pick up later in the season, that would be worth watching, but for now the outlook stays calm and manageable.
