Connecticut Wildfire, Smoke, and Air Quality Map

Fire season and landscape

Forest fire danger peaks in April and early May while the hardwood canopy is still bare, and again in dry falls, as in October 2024 when brush fires burned on the traprock ridges around Berlin. In most summers, the main statewide air quality influence is smoke from Canadian fires arriving on northwest flow.

State forests like Pachaug in the southeast and Tunxis in the northwest cover a notable share of a small, heavily wooded state, with traprock ridges running up the center of the Connecticut Valley. Nor'easters, tropical remnants, and flash flooding on short, steep rivers define the hazard profile at least as much as fire does.

• Traprock ridge fires in the Connecticut Valley burn in thin, rocky soils and register as satellite hotspots quickly, often before any perimeter is drawn.
• Canadian smoke typically reaches Connecticut on northwest winds, and the smoke layer shows the plume's approach across the Hudson Valley before local monitors move.
• Short, steep basins like the Naugatuck rise fast in heavy rain, and the river gauge layer reflects those swings within hours.
