Local Environmental Conditions
The area around this part of Covelo is heavily wooded, with some open grassland. A watercourse nearby means riverside vegetation is part of the local pollen picture. The surrounding woodland makes trees an important local pollen source. There is plenty of grass pollen here too. Roadside verges and patches of open ground provide further room for grasses and weeds.
Month by month, woodland and street trees lead off, with tree pollen peaking around mid-spring. Grasses take over, peaking around late spring and fading by midsummer. The season closes with a lower weed peak from early summer into early fall, mostly from roadside and field-edge plants. Here, temperatures range from around 5°C in the coldest month to around 25°C in the warmest, with most rain falling in the cooler months.

How often is the Covelo pollen forecast updated?
The Covelo pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Covelo 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 Covelo 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 Covelo, 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. |
