No notable pollen right now.
Last updated July 28, 2026
Pollen is essentially quiet across Costa Mesa today. Tree pollen, the only category with a reading, sits at none, meaning there is little to nothing in the air to bother even those with sensitive noses and eyes. It should be a comfortable day for spending time outdoors without much concern about allergy flare-ups. Looking ahead, tree pollen is expected to remain flat and negligible in the near term, so no significant change is on the horizon. This lull fits the season, since local trees such as Washingtonia, Trachycarpus, Syagrus, Nerium, and Pine typically release most of their pollen earlier in the year, well before midsummer. With tree activity dormant and grass and weed pollen not showing readings at the moment, this is generally a calmer stretch for allergy sufferers in the area.
