As I write this, it’s seven degrees outside. But only a few months ago I was sweating during a ceremony.
This ceremony was undercover and protected from the sun, but the air was stagnant and hot. The bride and groom anticipated the heat, but the solution was handing out paper fans which don’t get rid of the hot air guests are sitting in.
If you stand under a tree on a hot day, it will actually feel okay if there is a slight breeze. If heat will be a problem, I recommend renting a large fan for your ceremony. Try to position the fan so that in helps cycle new air into the room. Some guests, especially the older ones, may arrive 30 minutes before the ceremony even starts. Seat them in front of the fans so they’re a little more comfortable. If you’re worried about noise, turn off the fans right when the ceremony starts.
