Data-derived climate profile
How St Bernard's climate pattern fits together
mixed demand · low swing
Temperature varies within a narrow 29.1°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 69°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
St Bernard combines a compact 29.1°F annual temperature range with meaningful demand on both sides of the thermostat: 1,374 heating and 2,710 cooling degree days. The balance matters more here than either annual total in isolation.
The frost-free window extends for about 314 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
A moisture-range label is withheld because St Bernard's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from St Bernard's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like St Bernard, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from St Bernard's primary station: ST BERNARD (USC00168108). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for St Bernard; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for St Bernard comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
