What Mayville's climate means for you
Mayville runs 39°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.
Mayville, North Dakota runs an annual average of 39°F, ranging from a mean daily high of 51°F to a mean daily low of 28°F, per NOAA's 1991–2020 climate normals. July is typically the warmest month of the year, while January is the coldest. Drawn from station USC00325660, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Mayville sees about 23.9 inches of precipitation a year, 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 13 and the first fall freeze near September 27. On the energy side, 9,628 heating degree days and 344 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Mayville 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.
