What Grand Forks's climate means for you
Grand Forks runs 40°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.
In Grand Forks, North Dakota, the NOAA 1991–2020 climate normals put the annual average temperature at 40°F, ranging from a mean daily high of 51°F to a mean daily low of 29°F. July is typically the warmest month of the year, while January is the coldest. As thirty-year averages computed from station USW00014916, these numbers smooth out year-to-year noise into a working baseline for a typical month.
Grand Forks averages 21.7 inches of precipitation a year, with 48.4 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 134 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 27. As for energy demand, 9,533 heating degree days and 384 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Grand Forks scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
