Halloween Extremes & Warming October Nights

With Halloween a couple days away, Climate Central examines Halloween extremes—the coldest, warmest, rainiest, and snowiest October 31sts’ on record for 242 cities—as well as the warming trend of October nights. 

From 1970 to 2019, 88% (212) of the 242 cities analyzed had an increase in their October minimum temperatures, consistent with the overall fall warming trend caused by climate change. 

Traditional October and fall festivities, like trick-or-treating and pumpkin picking, may undergo some changes as our climate warms. Increased global temperatures can help amplify wet and dry conditions regionally, and as a result, threaten cocoa bean and pumpkin harvests.
