Pollen in Berkeley, CA

About pollen in Berkeley

Berkeley is enjoying a quiet stretch when it comes to pollen today. Tree pollen, the only category with a reading, is essentially absent, meaning those prone to seasonal allergies should find little to react to in the outdoor air right now. It’s a good day to be outside without much concern about airborne irritants from trees. Looking ahead, this calm is expected to hold, with tree pollen staying at negligible levels through the near term. That fits the season, since local trees such as ash, liquidambar, tristaniopsis, pittosporum, and prunus typically release most of their pollen earlier in the year, well before summer sets in. With grass pollen usually easing by this point and ragweed season still weeks away, the overall pollen picture in Berkeley should remain mild for now.

What to do today

• Pollen is minimal today, so it's a great time to be outside.
• No special pollen precautions are needed right now.
