Local Environmental Conditions
Nearby, a short distance from here, water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. Located a short distance from here, this area has woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Along the waterway, river oak releases pollen first, getting an early start, typically cresting between July and August. Woodland eucalypt and wattle pick up the pace next, through late winter into spring, building to its sharpest point across August and September. Grass pollen becomes the dominant allergen through spring, peaking in November, then persisting at a reduced but still meaningful level into the new year.

When is pollen season in Berkeley?
How often is the Berkeley pollen forecast updated?
The Berkeley pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Berkeley come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Berkeley based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Berkeley, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
