Rain contingency plan for your wedding: the complete guide

Key takeaways

• A rain contingency plan must be written into your venue contract, in black and white, before you pay the deposit. The phrase "if it rains we'll use the indoor room" means nothing without contractual backing.
• Marquees and temporary structures need to be booked four to six months ahead during peak season. In June, some companies close their diaries even earlier.
• The decision to activate your contingency plan should be made 48 to 72 hours before the event: not sooner (seven-day forecasts are not reliable enough) and not later (there is no time left to set anything up).
• Your florist and décor team need to know about the rain scenario from the initial brief, not the day before.
• Wedding insurance covers cancellation or postponement due to extreme weather, not a straightforward change of space. Reading the small print is essential.

According to Spain's National Statistics Institute figures from 2022, around 172,000 weddings take place in the country each year, and a significant proportion choose outdoor venues between May and October. What many couples have not resolved when they sign with a venue is exactly what happens if it rains on the day: who makes the call, how many hours in advance, what additional cost is involved and how it affects décor that is already in place.

Below we walk through the real options for a rain contingency plan and the mistakes that repeat themselves season after season, because the vast majority are entirely avoidable.

The mistake of confusing "having a Plan B" with "having actually booked one"

Many couples leave their venue meeting reassured that "if it rains, we'll use the indoor room." But that phrase is worth very little if it is not written clearly into the contract. Some venues charge a supplement for indoor use when the original booking was for an outdoor space. Others have the indoor room occupied by a separate event. And some simply do not have enough capacity to accommodate all the guests from a wedding designed for a 400-square-metre terrace. All three situations happen, and all three are a serious problem on the day of the wedding.

Before signing with any venue, it is worth checking exactly what the adverse weather conditions clause covers, whether the alternative space has the same capacity as the outdoor area and how far in advance you need to notify them of any change. If the contract says nothing on any of these points, ask for it in writing before paying the deposit.

Real options for a contingency plan

Marquee or temporary structure

This is the most versatile solution for weddings at rural estates, private gardens or outdoor spaces with no permanent cover. Marquees have come a long way: they are no longer just white canvas with a makeshift feel. There are frame structures with glass walls that let you look out onto the garden even in the rain, linked pagoda modules and clear-roof marquees that preserve the sense of being outdoors.

Costs vary. A pagoda marquee for around 80 guests can range from roughly £1,200 to £2,500. A larger structure for 150 guests, with a wooden floor, integrated lighting and side panels, can easily reach £4,000 to £9,000. These figures typically exclude climate control, which in summer is almost essential once the sides are closed.

Booking lead time is the critical factor. During peak season (May to September), specialist event structure hire companies work with very tight diaries. Booking four to six months ahead is standard; for popular dates such as the first two weeks of June, some companies close their diaries even earlier.

The venue's own indoor space

If the venue has its own indoor room, this is logistically the simplest option. But it requires advance planning: the floral décor, table layout and lighting need to be designed for both scenarios from the outset. Arriving the day before with the idea of "if it rains, we'll just move everything inside" without having coordinated this with the floristry and catering teams is a guaranteed source of chaos.

Some couples choose to design their décor so that it works in both spaces: table centrepieces that can be moved without being dismantled, festoon lighting that can be replicated indoors, a wedding arch that fits through the ballroom door. That dual planning involves additional coordination time and cost, but it removes most of the stress if the switch needs to happen.

Moving to an alternative covered venue

Less common, but sometimes the most elegant solution: booking a covered alternative space from the start as the official contingency plan. This could be a restaurant with a glazed terrace, a winery with a covered nave or a sheltered courtyard. It means having two contracts and coordinating two separate teams, but it provides genuine peace of mind because the space is guaranteed.

This option makes most sense when the original wedding venue has no indoor alternative of its own: a private beach, a botanical garden, a rooftop.

When to make the call

The most practical approach: decide 48 to 72 hours before the event.

With that lead time, weather forecast models are already accurate enough for specific locations. Waiting until the day before may be too late to erect a marquee, reorganise the floristry or inform catering suppliers that the space has changed. Deciding a week out based on a seven-day forecast is also premature: models at that range carry a considerable margin of error.

Agreeing with your coordinator or wedding planner in advance who makes the call, and on what specific criteria (precipitation probability above 60%, rain forecast during the ceremony window, and so on), avoids difficult conversations at the worst possible moment.

Why décor is central to all of this

A contingency plan that does not include your florist and décor team is not a complete plan. Many elements designed for outdoor use do not translate directly indoors: oversized floral arches may not fit through a standard door. Candles that work beautifully outside in the open air can create issues inside depending on the type of space. And the natural light calculated for a terrace at seven in the evening simply does not exist in a windowless ballroom.

The conversation with your florist and decorator should explicitly address the rain scenario. Raise it as part of the initial brief, with the same matter-of-fact tone as discussing flower colours or budget. Which elements can be moved? Which would need rethinking? Does the team have availability to reorganise on the morning of the event if needed?

Indoor wedding from the start: the safest option?

Some couples, faced with the uncertainty, decide to go straight for an indoor venue and remove the problem entirely. This is a completely valid choice, and in certain seasons it makes a great deal of sense: in November or February, for example, the rainfall probability across much of the UK and Spain makes an outdoor bet a fairly risky one. But it is worth making that decision with actual data rather than fear alone.

The time of year matters enormously: the likelihood of rain at a July wedding in Seville is very different from that at an October wedding in San Sebastián or a September wedding in the Scottish Highlands. You can find more context on this in the article on the best season to get married in Spain, where we compare average rainfall by region and month.

And if the underlying question is deeper, if what you are really asking is "indoor or outdoor?", that is covered in more detail in indoor wedding vs outdoor wedding.

Wedding insurance and rain: what it covers (and what it does not)

Wedding insurance policies do exist and some include cover for adverse weather conditions, but the terms vary considerably between policies. In general, they cover cancellation or postponement costs when rain makes the celebration impossible. A straightforward change of space, however stressful, typically falls outside coverage. That distinction matters.

Before taking out a wedding insurance policy, read carefully what the specific policy defines as an "adverse weather condition": whether it requires an official declaration, whether it sets a minimum rainfall threshold, whether it covers only the ceremony or also the rec
