A Slightly Cooler Louisiana Experience
At 65.3°F, Winn Parish is cooler than the Louisiana state average of 67.0°F. This makes it one of the more temperate parishes in the state, largely due to its north-central location. It offers a slight reprieve from the more extreme heat found in the southern parishes.
