Before you book the garden
Plan the version
you can still host.
An outdoor event needs a named backup before the deposit, not a hope that the day will be fine. This guide helps you define the weather that changes the plan, check that the backup fits the same guests, and decide who makes the call.

Name
The weather that makes this format fail
Backup
Cover on site, a real indoor room, or a changed format
Write down
Who decides, by when, and what it costs
Tell guests
Only when the instruction would change what they do
01
Name the weather that breaks this event
Rain is not the only failure. Wind matters for ceremonies, paper and tall furniture. Heat matters for a long meal in direct sun. Cold and early darkness matter for a dinner that starts late. Write the conditions under which you would not keep the planned format, using the season and time of day you actually have. A plan that says “we will see on the day” is a plan to decide under pressure, with suppliers already loaded for one version.
Rain
Wind
Heat or cold
Wet ground under furniture
Darkness if the event relies on daylight
A forecast deadline you can act on
02
Pick a backup that holds the same event
A backup is only real if the guests, the format and the end time still fit. Cover on site, such as a tent or a verandah, has to fit the furniture and the catering path, and someone has to know who orders and installs it. An indoor room has to be available for the whole time you would need it, not only for a speech. Changing the format, such as shortening the outdoor ceremony, is a backup only if guests and suppliers have been told what changes. If the indoor room holds fewer people, reduce the guest count or do not call it the backup.
03
Put the decision rule in the agreement
Ask the venue who may call the change, the latest time that call can be made, and whether the backup space is included in the hire or billed only if used. Ask what happens to catering, music and rentals if the call is late. Write the answers into the agreement before you pay a deposit that assumes good weather. A verbal “we can always move inside” is not a backup if that room is also booked, unheated, or smaller than the invite list.
Who decides

Whether the backup is included
Cost if you switch
Cost if you hold the backup and do not use it
What suppliers must be told
04
Order rentals for the version you might host
Flooring, weights, lighting, heaters and side walls are part of an outdoor plan, not decorations added after a forecast. Ask the rental company which items change if you move inside, and whether they need to know before the truck leaves. The rental cost guide explains how to compare the delivered scope. Do not assume a dry-hire quote includes the labour to rebuild the room in the rain.
05
Tell guests when their actions change
Guests need a message when the entrance, the dress they were advised to wear, or the start time changes. They do not need every forecast discussion. Decide the channel, who sends it, and the last time you can still reach travelling guests. Keep one version of the instruction. A host texting one door while the venue’s sign points to another is how people miss the backup you paid for.
06
Indoor events still need a smaller version
If the whole event is inside, you may still be exposed at arrival, in a courtyard welcome, or on a journey between two buildings. Apply the same questions to that gap: wet ground, coats, a step-free route that is not the garden, and a delay if guests are moving between sites. For a Berlin address, use the local guide to check the journey and any sound limits. Weather does not replace those checks.
