What Heidelberg's climate means for you
Heidelberg runs 56°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.
Heidelberg, Kentucky runs an annual average of 56°F, ranging from a mean daily high of 67°F to a mean daily low of 44°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 USC00153741, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Heidelberg averages 49.7 inches of precipitation a year, with 18.2 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 188 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 17 and the first fall freeze near October 22. As for energy demand, 4,509 heating degree days and 1,123 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Heidelberg scores 78/100 (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.
