July is typically the warmest month of the year, while January is the coldest.

Anyone planning to live, garden, or travel in Clam Lake should weigh precipitation alongside temperature: the annual average runs 33.9 inches, predominantly as rainfall. The frost-free season averages 137 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 16 and the first fall freeze near September 30. And on the energy front, 9,412 heating degree days and 201 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Clam Lake scores 54/100 (Moderate), 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.
