Why Ridges Are Different

There is a particular kind of weather that catches hillwalkers out, and it nearly always happens on a ridge. In the valley the morning looked reasonable: a bit of cloud on the tops, a breeze you could lean into without thinking twice. Two hours later you are on an exposed shoulder at 800 metres with the wind at forty miles an hour, horizontal rain finding the gap between your hood and your collar, and the path ahead vanishing into grey. Ridges amplify everything. You have no shelter, no easy escape route to either side, and the ground beneath your boots is often the wettest, greasiest rock on the hill.

The good news is that the decisions that keep you safe on a ridge are simple, and most of them are made before the situation gets genuinely serious. The trick is recognising the moment to act. That moment is almost always earlier than it feels.

Turn Back Before You Have To

The single most useful skill on a ridge in deteriorating weather is knowing when to stop going up. Not when you are frightened, not when someone in the group is struggling, but earlier — the point at which continuing would mean committing yourself to a descent you would not choose in these conditions.

Ask yourself a blunt question at every reasonable pause: if the cloud came down completely in the next ten minutes, could I get off this ridge safely? If the answer is no, you have already gone too far for the weather you have. Turning around at that point is not defeat; it is the whole point of planning.

• Set a turnaround time at the car park and stick to it, weather aside. It is the most reliable decision aid you have.
• Name your escape routes as you go up — a broad shoulder, a marked path down, a bothy or a forest track. If you cannot name one, you are on a committing ridge.
• Watch the cloud base, not the forecast. If the tops have been swallowed since you set off and the wind is veering, the day is telling you something.

Coming down a ridge you already know is far quicker and safer than pressing on into cloud and hoping a descent you have never walked will be straightforward. It rarely is.

Layer Up Before You Get Cold

Wind chill on an exposed ridge can knock ten degrees off the felt temperature, and wet plus windy is the combination that drains people fastest. Add clothing at the first sign of trouble, not when you are already shivering. Shivering is late.

• Stop in the lee of a rock, bank or cairn if you can, even if it means walking fifty yards off line. Sheltering while you dress makes an enormous difference.
• Put your waterproof shell on over everything before the rain soaks your mid-layer. Once a fleece is wet it insulates poorly and dries slowly.
• Hat, gloves and hood up. Most heat loss is from the head and hands, and cold hands make map work, buckles and torch switches genuinely difficult.
• Check your group. The quietest person is often the coldest. Ask directly whether anyone's hands or feet have gone numb.

If someone is properly cold — clumsy, slurring, unable to do up a zip — that is an emergency, not a discomfort. Get them out of the wind, into dry layers and a sleeping bag or bothy bag if you carry one, and get moving downhill towards shelter as soon as you can.

Eat and Drink on the Move

Ridge weather burns energy at a rate most walkers underestimate. Fighting wind, balancing on wet rock and concentrating on navigation all cost calories, and hunger makes bad decisions feel reasonable.

Get something into you the moment you stop to add layers. Flapjack, oatcakes, nuts, a squashed sandwich, a handful of jelly babies — it does not matter much. What matters is that it happens before the wobble, not after. A flask of hot sweet tea or soup is worth its weight in gold on a cold ridge, and it lifts a group's mood faster than almost anything else.

Keep drinking too. It is easy to forget in the rain, and mild dehydration sharpens the same edges as cold: poor balance, poor judgement, poor temper.

Navigate by Compass When the Cloud Drops

Cloud descends faster than any descent you have planned. One minute you can see the col ahead; the next you have perhaps thirty metres of visibility and no horizon at all. This is when a GPS unit or phone can fail — cold batteries, wet screens, a cracked case — and when the compass in your pocket earns its place.

• Stop and take a bearing from your current position to a definite point on your descent route: a col, a path junction, a stream confluence, a wall corner.
• Walk on the bearing, counting paces to check your distance. Keep the map folded to the relevant section and orient it with the compass.
• Use handrails. A stream, a fence line, a wall or a ridge edge running in your direction of travel is far easier to follow in poor visibility than a faint path.
• Move deliberately, not quickly. A slip on wet rock in whiteout costs far more time than a slow, careful descent.

If you are unsure of your position, say so out loud. Groups that quietly hope the person in front knows the way are the ones that end up benighted. Get the map out, agree the plan, and walk it together. And if the weather closes in completely, be honest: dropping off the ridge into a known valley route is nearly always better than pressing for a summit you cannot see.

Getting Down Safely Is the Day's Success

Nobody remembers the summit they did not reach. They remember being cold, being lost, or being the one who had to be helped down. A ridge walked in good weather is a joy; the same ridge in a hoolie is a serious outing, and treating it that way is not timid — it is experience.

So turn early, layer up before the shiver, eat before the slump, and navigate before the cloud swallows you. The hill will still be there next weekend, and you will enjoy it more.
