Local Environmental Conditions
This location in Newport Beach is surrounded mainly by open water, which covers around 64% of the nearby area, with a good deal of built-up land. Oak, plane tree and willow are among the allergenic trees in the wider area. Grasses, pigweed and mugwort growing in the surroundings are the main non-tree sources of pollen.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, plane tree and willow are in full flower. Grasses take over in early summer and keep pollen in the air into mid-fall. The season closes with pigweed and mugwort from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen.

How often is the Newport Beach pollen forecast updated?
The Newport Beach pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Newport Beach 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 Newport Beach 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 Newport Beach, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
