Manzanillo's air quality benefits from its exceptional Pacific Ocean and Manzanillo Bay coastal position in Colima, with consistent Pacific maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the major Pacific container port operations, tourism, and fishing corridor contribute local sources, while the outstanding Pacific coastal exposure and the Sierra Madre Occidental rising inland create dramatic topographic variation and Manzanillo generally maintains moderate to good conditions for a major Mexican Pacific port city throughout most of the year.

Frequently Asked Questions
Is air quality bad in Manzanillo right now?
On 9 August 2026, overall air quality in Manzanillo is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 5:00 PM (PM10: 100/100).
Will air quality be worse tomorrow in Manzanillo?
On 10 August 2026, air quality conditions in Manzanillo will be better than today, with AQI forecast at poor at 74.0/100. Pollution peaks around 9:00 PM (PM10: 74.0/100).
When is air pollution at its worst in Manzanillo?
In Manzanillo, road traffic, port and shipping activity, together with seasonal tourism traffic are the main local sources, with conditions worsening when maritime winds die down. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Manzanillo 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.
