What Terrytown's climate means for you
Terrytown runs 70°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USC00168941 feeding NOAA's 1991–2020 climate normals, Terrytown, Louisiana averages 70°F a year, ranging from a mean daily high of 79°F to a mean daily low of 62°F. July 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.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Terrytown receives roughly 65.9 inches of precipitation each year, with negligible snowfall. The frost-free season averages 333 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 1 and the first fall freeze near December 31. For energy use, 1,206 heating degree days and 3,150 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Terrytown 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 July-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.
