What Chicago Palwaukee's climate means for you
Chicago Palwaukee runs 51°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 51°F, ranging from a mean daily high of 59°F to a mean daily low of 42°F is what the NOAA 1991–2020 climate normals report for Chicago Palwaukee, Illinois. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00004838 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Chicago Palwaukee should weigh precipitation alongside temperature: the annual average runs 32.3 inches, predominantly as rainfall. The frost-free season averages 190 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 19 and the first fall freeze near October 26. And on the energy front, 6,085 heating degree days and 933 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Chicago Palwaukee scores 68/100 (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.
