The county has a [[Humid continental climate#Warm summer subtype|humid continental climate]] (classified as Dfb in [[Köppen climate classification|Köppen]]) with warm summers and cold snowy winters. Data from the Peninsular Agricultural Research Station north of the city of Sturgeon Bay gives average monthly temperatures ranging from {{convert|68.7|F|C}} in the summer down to {{convert|18.0|F|C}} in the winter. The moderating effects of nearby bodies of water reduce the likelihood of damaging late spring freezes. Late spring freezes are less likely to occur than in nearby areas, and when they do occur, they tend not to be as severe.<ref>{{cite book |url = https://www.nrs.fs.fed.us/pubs/gtr/gtr_nc204.pdf |title = A Climatology of Late-spring Freezes in the Northeastern United States  |first1= Brian E. |last1 =Potter |first2 = Thomas W. |last2 = Cate |publisher = United States Forest Service |id = General Technical Report NC - 204 |year = 1999 |page = 2}} Also see maps on pp. 15 and 29.</ref>
