Pollen in San Bernardino, CA

About pollen in San Bernardino

Mid-November in San Bernardino tends to be a quieter stretch for pollen overall. Local trees such as oak, olive, and sycamore have largely finished their active cycles for the year, and grasses across the valley are mostly dormant this time of season, so most residents should find outdoor conditions fairly comfortable right now. Looking ahead, this lull is typical for late fall in the Inland Empire, as the region sits between the fading ragweed and late-season weed activity of early autumn and the start of winter dormancy. Any changes over the next few days are likely to be minor, with conditions staying mild unless a shift in weather stirs up residual weed or mold activity. Those who are especially sensitive may still want to keep an eye on local conditions as the season transitions, but significant pollen activity is not expected to return until trees begin budding again in late winter or early spring.
