Prepare one weather backup for an outdoor outing

A useful weather backup gives the day a clear alternative without creating a second full itinerary that nobody has agreed to follow.

1. Choose one nearby indoor activity that fits the same group, approximate duration and travel area. Check its opening information, entry requirements and availability rather than assuming you can arrive without a booking.
2. Decide when to review the forecast and any official venue notices. Agree on a simple switching decision, such as moving indoors if the outdoor organiser cancels, and name who will tell everyone.
3. Save the backup's address and the route from your starting point. Check how changing the plan affects existing reservations and transport, and avoid making incompatible bookings you do not intend to use.

Tell companions the final plan before they leave. For severe weather or closures, follow local official guidance rather than treating the backup as a reason to travel regardless.
