What Gulfport - Biloxi's climate means for you

These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Gulfport - Biloxi, Mississippi runs an annual average of 68°F, ranging from a mean daily high of 77°F to a mean daily low of 59°F, per NOAA's 1991–2020 climate normals. July is typically the warmest month of the year, while January is the coldest. Drawn from station USW00093874, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Gulfport - Biloxi sees about 62.8 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 283 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 23 and the first fall freeze near December 3. On the energy side, 1,507 heating degree days and 2,749 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Gulfport - Biloxi 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.
