About Lincoln County Weather
Milder Maine living along the coast
Lincoln’s 46.1°F annual average temperature is several degrees warmer than the state average but trails the national median. The coastal location creates a more predictable and moderate climate.
One of the state's warmest counties
Its 46.1°F average is well above the 43.8°F Maine baseline. This makes it one of the more hospitable regions for those wary of Maine's extreme inland cold.
Similar to neighboring Knox County
Lincoln shares a nearly identical temperature profile with Knox (46.0°F) and Cumberland (45.3°F). It is notably warmer than the inland state average, benefiting from the sea air.
Manageable winters and infrequent heat waves
The county sees 78.7 inches of snow and only 2 days of extreme heat annually. Winter temperatures average a relatively mild 25.3°F compared to the state's interior counties.
Coastal protection and standard winter prep
Residents should use weather-resistant building materials to handle the 49.2 inches of annual precipitation. Moderate winter gear is sufficient for the 25.3°F average winter temperatures.
