While it's wonderful to plan your outdoor concert on a day the Farmer's Almanac predicts sun and a light breeze, you've still got to have a back-up. If it rains on your outdoor concert, you want to be able to tell your paying customers when to come back for their money's worth.
Arrange for a weather plan that lets you fairly easily rebook everything should rain or hail get in the way of a good time. Even if you can't say for sure when the new concert will be, you'll be able to set tentative days, which can save you a lot of work. You don't want to be starting from scratch if the Almanac turns out to be wrong.
It's not much of a crowd pleaser when you have to refund everyone's money -- which, by the way, should be covered by your insurance.
