About pollen in Stockton

Pollen levels in Stockton are quiet today. Tree pollen is essentially absent, and grass pollen is running very low, so most people should notice little to no irritation outdoors. Overall, this is a calm stretch for allergy sufferers in the area. Looking ahead, grass pollen is expected to hold steady at a similarly low level over the next several days, with no significant increase in sight. Tree pollen should remain minimal as well, which fits the season — trees like liriodendron, pistacia, crape myrtle, privet, and sweetgum typically finish their pollen release earlier in the year, well before midsummer. With grass activity already tapering and weed season still weeks away, conditions should stay mild and manageable for now.
