Climate Insight: Rough Rvr Lake, KY

The NOAA 1991–2020 climate normals describe Rough Rvr Lake, Kentucky as a location with an annual average temperature of 57°F, ranging from a mean daily high of 69°F to a mean daily low of 44°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00156988, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Rough Rvr Lake receives roughly 51.5 inches of precipitation each year, with 4.4 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 17 and the first fall freeze near October 23. For energy use, 4,418 heating degree days and 1,421 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Rough Rvr Lake scores 72/100 (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.
