Local Environmental Conditions
The area around this site in Oceano is a patchwork of built-up land, open water and woodland. A nearby park adds mown lawns and planted trees to the local pollen mix. The key allergenic tree nearby is oak. Grasses also feature strongly, alongside pigweed and ragweed among the weeds. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Oak leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in early summer and easing off by early fall. Pigweed and ragweed bring a final peak from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

How often is the Oceano pollen forecast updated?

Does pollen in Oceano 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 Oceano 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 Oceano, 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 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. |
