Does Changing the Guard occur when its raining?

If the rain is heavy, or the forecast is for rain, the British Army may decide to curtail the ceremony. On such occasions, there will be a ‘Wet Change’ where the soldiers wear light overcoats and march without the ceremonial band. They will also protect their regimental flag (the ‘colour’), and guard movements will vary. However, sometimes the full ceremony goes ahead in the rain, and the decision to curtail the ceremony is usually made at the very last minute.
