Our weather in Indiana isn't predictable and it can be very uncomfortable when you add humidity to high tempuratures. Prepare for heat by making sure you drink a lot of cold water. Do your best to begin the ceremony on time, so your guests don't "cook" in the hot sun. You may even want to bring a cooler filled with cold water and popsicles for your guests to keep them cool.
When storm clouds are looming on the horizon, prepare to move your ceremony indoors, or bring umbrellas to protect your guests.
Pregnant Bride's need to be especially careful in the heat. Make sure you have plenty of water and bring saltine crackers to munch on just before the ceremony to keep your stomach settled. That way, you'll be able to enjoy this very special day without recalling any ill effects.
Not sure what to bring? Prepare for the worst and expect the best -- you won't be disappointed!
