Key West Lighthouse's air quality benefits from the Key West island's exceptional Atlantic Ocean and Gulf of Mexico dual-coastal position, with consistent trade winds providing outstanding maritime ventilation. Vehicle traffic on Whitehead Street contributes modest local sources, while the extraordinary dual-ocean trade wind exposure generally maintains the Key West Lighthouse among Florida's most reliably ventilated historic maritime landmarks throughout most of the year.

Frequently Asked Questions
Is air quality bad in Key West Lighthouse right now?
On 9 August 2026, overall air quality in Key West Lighthouse is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 12:00 AM (PM10: 100/100).
Will air quality be worse tomorrow in Key West Lighthouse?
On 10 August 2026, air quality conditions in Key West Lighthouse will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 5:00 PM (PM10: 100/100).
When is air pollution at its worst in Key West Lighthouse?
This landmark in Key West sees air quality shift through the year. In short, the wetter summer months often see cleaner air, as frequent afternoon storms wash pollution out quickly, whereas the drier months from roughly November through April bring the highest risk of wildfire and prescribed-burn smoke. Inland areas tend to see more smoke buildup than locations closer to the coast.
Are air quality levels in Key West Lighthouse 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.
