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

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. ST Johns Industrial sees about 9.1 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 160 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 3 and the first fall freeze near October 10. On the energy side, 4,861 heating degree days and 932 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, ST Johns Industrial 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 December-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.
