When thinking about attire, choose lightweight dresses and natural fibers for the bride and bridesmaids, and ditch the vests and cummerbunds for the guys. If the bridal party will be changing into their wedding clothes at the church or hall, arrange to have the air conditioning turned on or the windows opened early, and bring a small fan to keep the bride cool. Keep reception foods light and cool. Make sure to have plenty of ice and cold drinks available. Cold soups like gazpatcho, lime-cucumber or melon can cool your guests off from the beginning of the meal.
Summer is the perfect season for an outdoor ceremony.
If you live in an area where the weather is very warm, be sure to think about the comfort of your wedding guests. A covered area, whether it's shaded by trees or by a canopy, will help keep guests cool. Check for shade and insects. Your wedding won't be much fun if guests must stand in the blazing sun and will be plagued by gnats. If there are flowering plants at your location, consider incorporating their colors into your wedding decorating scheme.
