July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.

Anyone planning to live, garden, or travel in Sidney should weigh precipitation alongside temperature: the annual average runs 18.2 inches, with 28.8 inches typically falling as snow. The frost-free season averages 149 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 8 and the first fall freeze near October 4. And on the energy front, 6,373 heating degree days and 735 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Sidney scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
