When do you decide to move the wedding indoors? The morning before, at a time you set now, by a person you name now, using a trigger you pick now. Mine, if you want a starting point: a fifty percent chance of rain during the ceremony hour, or a forecast low under sixty, and the call belongs to one person who is not one of the two of you. That is the rain call, and it is the single most valuable decision on the plan B card, because on the morning of a wedding nobody is thinking clearly, the forecast changes hourly, and half the family has an opinion. Decide the rules while it is sunny. Then, on the day, there is nothing to decide.

Who makes the call

Not you. You will be getting ready, and you are the least objective people in the building. Not the venue alone either, because the venue's interest is the room flip, not your photos. The best decider is your coordinator, or a parent, or a friend with a level head, who has walked the outdoor space and the backup space with you and knows what you would choose. Write the name on the card. Give that person the forecast, the venue's number, and your permission in advance, out loud, so they never have to ask.

By when

Ask the venue and, if you have one, the tent company for their own deadlines first. A tent hold has a release date and time in the contract, and a venue that has to flip a room needs hours, not minutes. Whatever their deadline is, yours comes before it. My suggestion is the morning before the wedding, when the forecast for the ceremony hour is finally worth something. Calling it the morning of works only when the backup is already set up and waiting, and even then, the later you call it, the more people have to move at once.

What moves with it

This is the part couples underestimate. Moving the ceremony inside is not one change, it is a dozen.

  • The ceremony seating. Usually guests sit at their dinner tables, which means the room is set before they arrive and the flip you planned does not happen.
  • The cocktail hour. With a room flip, add thirty minutes; the builder shows this as a rain-plan line and the whole night shifts behind it.
  • The sound. The ceremony system, the mics, and the power all move, and whoever runs them needs to know where the new outlet is.
  • The photos. The indoor spots get picked at the site visit, not after the first drops, and the photographer's plan for the family formals moves with them.
  • The florals and the arch. Some move, some don't. Decide which.
  • The aisle, the officiant's spot, where the two of you enter from, and where you go after the recessional.
  • The send-off. Bubbles work in a doorway, petals don't work on a wet lawn, and sparklers are fireworks under Massachusetts law, wet lawn or dry.

Some plans are partial: ceremony indoors and dinner outside under the tent, or the reverse. Wind and heat are triggers too. A tent in a coastal wind is a different problem from rain, and a sunny ninety-degree afternoon on a lawn with no shade needs water and a plan just as much as a wet one does.

Who tells the guests

The guests need to hear it once, from you, before they leave the hotel: a line on the wedding website, a text from the wedding party to anyone who won't check it, and a sign at the entrance for everyone else. Then the MC says it once more at the top of the ceremony, in one sentence, with a smile, and nobody mentions the weather again for the rest of the night. Guests take their cue from the room. If the two of you are not upset about it, they won't be either.

The supplies

Umbrellas (enough for the wedding party and the parents, not the whole room), towels, blankets or fans depending on the month, bug spray, sunscreen, a water station, and a mat for the aisle if the ground is soft. Assign them to a person and a car. The rain plan you cannot find at 3 o'clock is not a plan.

The weather section of the Plan B Card asks for exactly this: what is outdoors, the backup for each, the decider, the deadline, the trigger, and the supplies, and it hands the timeline change to the Run of Show so the vendor copy prints both versions.

Quick answers

  • What if the forecast is fifty-fifty? That is why you picked a number in advance. At your trigger, you move. No re-votes.
  • Can we wait and see on the morning of? Only if the indoor setup is already built and every provider knows both plans. Otherwise you are gambling with the room flip.
  • Will the indoor ceremony feel worse? Not to your guests. It feels worse to you for about ten minutes, and then someone you love is walking toward you and it doesn't.

Make the call before the day so the day doesn't make it for you.
