Which tents hold up in wind, and how to pitch for it

Shape first

A geodesic dome has multiple pole crossings and lots of small panels, so no single area of fabric can build up much load. It is the shape that survives, and the reason it costs headroom is that the same geometry cannot also give you vertical walls.

Big flat panels flap. The recurring complaint about large rectangular trekking-pole flies is not that they fail but that the noise makes them unsleepable in wind. Hexagonal footprints — six smaller panels under balanced tension — are noticeably quieter and stiffer for the same weight.

A tunnel is extremely strong end-on to the wind and the weakest shape here broadside. That is not a flaw, it is a pitching instruction.

Then the pitch

Every guyline, every time it is forecast to blow. The single most repeated lesson from people whose tents came down is that the guylines were coiled in the bag.

Stakes are the usual failure point, not poles. In sand, snow or loose duff, bury a stake sideways as a deadman, or tie off to rocks. People who have been through a bad night describe anchoring with rocks, not with better pegs.

Point the low, narrow end at the wind, and if you can, put the doors on the lee side — a door that is not taking wind is a door you can still open at 3am.

What does not save you

A higher hydrostatic head, a more expensive fabric, or a lighter pole set. Wind performance comes from shape, tension and anchors — the three things that cost nothing.
