Local Environmental Conditions
Richmond's typical vegetation carries through to Point Richmond, a historic waterfront neighborhood on San Francisco Bay, so pollen timing here matches the wider city rather than running on its own schedule. Exposure here depends mainly on how much tree and lawn cover surrounds the immediate site.
Like the rest of Richmond, Point Richmond experiences a season that opens with olive and acacia from January before eucalyptus peaks during February. Grass pollen rises through March and April, and light weed pollen carries into September. Mild year-round temperatures push the pollen calendar earlier than in most of the country, consistent with the wider Richmond area.

How often is the Richmond pollen forecast updated?

Does pollen in Richmond 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 Richmond 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 Richmond, 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. |
