Local Environmental Conditions
Around this site in Avila Beach, traffic is light and there are few concentrated sources of air pollution. The open grass and scrubland around the area can add dust in dry weather and smoke from occasional fires. Breezes off the nearby water usually help clear pollutants away. Pollution carried in from the wider region can also raise levels at times.
Air near roads is often at its worst from January to March, when nights cool to around 12°C and the air turns still. Later in the year, with summer temperatures averaging only about 19°C, ozone rarely becomes a serious problem. The risk of wildfire smoke peaks from June to October, when dry vegetation burns easily.

Later in the year, with summer temperatures averaging only about 19°C, ozone rarely becomes a serious problem. The risk of wildfire smoke peaks from June to October, when dry vegetation burns easily.
Are air quality levels in Port San Luis RV Campground based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
