Be Beautiful, Whether the Weather
An outdoor wedding can be gorgeous -- and incredibly risky. Have some common sense and always have a backup plan. Whether it's a banquet hall nearby, a ready-to-go tent or a gazebo, be sure to keep a secondary venue on hand in case of downpour or hail.
But don't think you're off the hook if the sun is shining on your big day! Even in the most beautiful weather, outdoor weddings have their own sets of hazards. For the sake of your guests' comfort, try to time your outdoor ceremony in order to miss the hottest hours of the day (roughly 10 a.m. to 3 p.m.). If you must say "I do" at noon, see if you can book a venue with a bit of shade.
Be aware of insects and sun, and consider keeping sunscreen and bugspray on hand in case someone comes unprepared.
