What Carlyle Rsvr's climate means for you
Carlyle Rsvr 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.
An annual average temperature of 56°F, ranging from a mean daily high of 66°F to a mean daily low of 46°F is what the NOAA 1991–2020 climate normals report for Carlyle Rsvr, Illinois. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00111290 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Carlyle Rsvr sees about 45.9 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 206 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 6 and the first fall freeze near October 29. On the energy side, 4,780 heating degree days and 1,438 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Carlyle Rsvr scores 78/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
