Climate Insight: Saint Bernard, AL

An annual average temperature of 62°F, ranging from a mean daily high of 73°F to a mean daily low of 50°F is what the NOAA 1991–2020 climate normals report for Saint Bernard, Alabama. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00017157 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

On PlainClimate's composite comfort index, Saint Bernard scores 68/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
