I first mentioned rain cards when I discussed the importance of having a backup plan for outdoor weddings. In that post I told you that:
Rain cards are an enclosure that you can include in your invitation set and they are the best way to inform your guests of your backup plan should it rain. In this way, they will know ahead of time where to go if it rains as opposed to having to call and or wander around trying to figure out where to go.
In sum, rain cards serve two purposes: to inform your guests that your wedding is taking place outside and to let your guests know of your back up plan or alternate location ahead of time. So, if you are having an outdoor wedding or hosting your wedding in an area that is prone to inclement weather, for example, on the coast during hurricane season, you should enclose a rain card with your invitations.
