What ST Bernard's climate means for you
ST Bernard runs 69°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 USC00168108 feeding NOAA's 1991–2020 climate normals, ST Bernard, Louisiana averages 69°F a year, ranging from a mean daily high of 77°F to a mean daily low of 60°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.
Beyond temperature, ST Bernard averages an uncharted amount of precipitation annually, predominantly as rainfall - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 314 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 4 and the first fall freeze near December 15. Turning to energy use, 1,374 heating degree days and 2,710 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, ST Bernard scores 80/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings August-driven heat, and winter brings January-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
