Local Environmental Conditions
Monterey Peninsula Country Club's Pebble Beach setting features Monterey cypress, coastal live oak, and coastal sage scrub as the main pollen sources across the Shore Course, with exposure varying between the exposed Pacific Ocean-facing holes and the more sheltered inland sections. The Pacific Ocean position means strong onshore marine winds frequently disperse pollen, while the coastal California climate advances the season and mugwort extends exposure into September.
The pollen season at Monterey Peninsula Country Club – Shore Course mirrors Monterey overall, starting with olive and acacia in January with eucalyptus joining in and continuing through February. Grass pollen then peaks through March and April, and light weed pollen carries into September. The Southern California Mediterranean climate advances the season, and onshore Pacific breezes can periodically disperse pollen, a defining feature of the local season.

How often is the Monterey pollen forecast updated?

Does pollen in Monterey 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 Monterey 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 Monterey, 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. |
