Big Bay receives roughly 32.8 inches of precipitation each year, with 132.3 inches typically falling as snow. 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 22 and the first fall freeze near October 6. For energy use, 8,687 heating degree days and 264 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Big Bay scores 44/100 (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.
