Pollen in Rialto, CA

About pollen in Rialto

Pollen activity in Rialto appears minimal for this point in the season, and most residents should find the air relatively easy to breathe today. Mid-November typically falls in a quieter stretch for allergy sufferers in the region, after the valley's grasses have finished their main run and before any winter-blooming trees start to stir. Looking ahead, conditions are likely to remain calm through the next few days, consistent with the usual seasonal lull in Southern California at this time of year. Local trees such as olive, oak, and sycamore are mostly dormant now, with tree pollen not expected to pick up again until late winter or early spring. Grass and weed pollen, including ragweed, have largely wound down after their late-summer and fall peak, so sensitive individuals should get some relief in the near term.
