Climate Insight: New Roads, LA

The NOAA 1991–2020 climate normals describe New Roads, Louisiana as a location with an annual average temperature of 69°F, ranging from a mean daily high of 79°F to a mean daily low of 59°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00166686, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. New Roads receives roughly 58.5 inches of precipitation each year, with seasonal snowfall possible. Growing-season length varies with elevation and microclimate, with the last spring freeze near February 19 and the first fall freeze near December 5. For energy use, 1,522 heating degree days and 2,940 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, New Roads scores 82/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
