Climate Insight: Hammond, LA
Based on station USC00164030 feeding NOAA's 1991–2020 climate normals, Hammond, Louisiana averages 67°F a year, ranging from a mean daily high of 78°F to a mean daily low of 56°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.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Hammond sees about 64.2 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 256 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 8 and the first fall freeze near November 19. On the energy side, 1,797 heating degree days and 2,467 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Hammond scores 72/100 (Good), 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.
