International Falls, with its relatively central position in the North American continent, has a [[warm-summer humid continental climate]] ([[Köppen climate classification|Köppen]]: ''Dfb''), with long, bitterly cold winters and humid, warm summers and is part of USDA Plant [[hardiness zone]] 3a.<ref>{{cite web|url=http://planthardiness.ars.usda.gov/PHZMWeb/|title=USDA Plant Hardiness Zone Map|publisher=Agricultural Research Center, PRISM Climate Group Oregon State University|access-date=January 15, 2018|archive-url=https://web.archive.org/web/20140227032333/http://planthardiness.ars.usda.gov/PHZMWeb/|archive-date=February 27, 2014|url-status=dead}}</ref> January averages {{convert|5.0|°F|1}}, and lows reach {{convert|0|°F|0}} on an average of 57.2 nights annually.<ref name = NCDC /> Highs only reach the freezing point or above an average of 16.7 days in the months of December, January, and February, and the temperature often stays below freezing for weeks at a time during the winter. In the winter of 1978 to 1979, the temperature stayed below freezing for 101 days, from November 17 to February 25.<ref name = NCDC /> Seasonal snowfall averages {{convert|73.0|in|cm|0|abbr=on}}; due to the cold typically preventing significant melting for much of the winter, snow depths of {{convert|5|in|cm|abbr=on}} or more are seen on a majority of days from December through March.<ref name = "NCDC TXT KINL"/> Spring, and more especially autumn, are short but mild transition seasons. July averages {{convert|64.9|°F|1}}, with highs reaching {{convert|90|°F|0}} an average of only 2 days annually, and in close to 40% of years, the temperature does not rise that high. Precipitation averages about {{convert|25.37|in|mm|abbr=on}} per year, and is concentrated in the warmer months. The average window for freezing temperatures is September 14 through May 26, allowing a frost-free period of 110 days; however, the all-time record for the latest first freeze was set relatively recently on October 17, 2021, being over a month late.<ref name = NCDC /> Measurable snowfall (≥{{convert|0.1|in|cm|abbr=on|disp=or}}) arrives on average on October 18 and departs April 22.<ref name = NCDC /> The all-time record high temperature is {{convert|103|°F|0}}, set on July 22, 1923, while the all-time record low is {{convert|-55|°F|0}}, set on January 6, 1909, a range of {{convert|158|F-change}}; the record cold maximum is {{convert|-29|°F|0}}, set on the same day as the record low, while, conversely, the record warm minimum is {{convert|79|°F|0}} on July 16, 1898.<ref name = NCDC />
