What New Orleans's climate means for you
New Orleans runs 71°F a year - peaking in August, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USW00012916 feeding NOAA's 1991–2020 climate normals, New Orleans, Louisiana averages 71°F a year, ranging from a mean daily high of 79°F to a mean daily low of 63°F. August is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
New Orleans averages 63.4 inches of precipitation a year, with negligible snowfall, and that matters as much to daily life here as temperature does. The frost-free season averages 335 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 30 and the first fall freeze near December 31. As for energy demand, 1,176 heating degree days and 3,206 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 Orleans scores 80/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, August-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
