"Melting cakes and melting guests. Wilting flowers and wilting brides. A hot day can spell disaster for a wedding unless there's detailed preparation beforehand.

The United States, on average, experiences about 74 "mild weather days" every year, according to a 2017 study in the Journal of Climatic Change.

That is 74 chances to hold the perfect outdoor wedding with tolerable temperatures, low humidity and nearly no precipitation, according to Sarah Kapnick, a National Oceanic and Atmospheric Administration climate scientist and co-author of that study. She says it was inspired by frequent requests from worried friends to predict the weather on their wedding days."
