Pitching a Tent in Wind: Orientation, Stakes and Guylines
Wind turns tent fabric into a sail. Setting up in a breeze is manageable with a little order: keep everything attached to something heavy, secure the windward side first and use the guylines that came with the tent rather than leaving them in the bag.
Orient before you start
Most tents shed wind best when the narrow or lowest end faces into it. Lay the tent out with that end toward the wind and keep the door on the sheltered side so it does not fill with air when opened.
Keep the tent clipped to your pack or a partner's hand until the first stakes are in.
Stake in the right order
Stake the windward corners first, then insert the poles and raise the tent, then stake the remaining corners. Drive stakes at an angle leaning away from the tent, and in soft ground use longer stakes or bury them sideways as deadman anchors.
If the ground is rocky, tie lines around large stones instead of forcing stakes.
Use the guylines
Guylines transfer wind load from the poles into the ground and keep the fly taut, which stops flapping and prevents the fly from touching the inner tent. Attach them to the windward side at least, and tension them evenly.
Recheck tension before bed and after any change in weather, because nylon stretches as it gets cold and wet.
