Is it safe to climb An Teallach - Sgurr Fiona today?

Poor Today Wednesday 28 October

• Wind and gusts: Summit wind up to 40 mph, gusting 51 mph. That is past the Poor line (wind 40 mph or gusts 65 mph), when walking on exposed ground is hard and a fall more likely.
• Rain: 100% chance of rain, about 6.3 mm in all. A 60% chance or more makes the day Marginal on its own: wet rock is slippery and wet kit chills you faster.
• Cloud: Cloud cover averages 99% and humidity 100% at summit height. Air that close to saturation means the top is likely to be in cloud, so plan to navigate by map and compass. The forecast gives no cloud base height; the main peak page estimates one from the valley forecast.
• Temperature and wind chill: Up to 5°C at the summit, down to 1°C, feeling as cold as -6°C in the wind.
• Daylight: Sunrise 07:25, sunset 16:44: 9h 19m of daylight. The longest route listed here takes about 5h 30m there and back by Naismith's rule, before stops.

What the verdict covers, and what it doesn't

Peakify rates each day Good, Marginal or Poor from the forecast summit wind, gusts, chance of rain and wind chill. Wind of 40 mph or gusts of 65 mph make it Poor; wind of 25 mph, gusts of 45 mph, a 60% chance of rain or a feels-like temperature of -8°C or below make it Marginal. That is all it measures: the weather forecast at the summit.

It does not know your fitness or experience, whether you can navigate in cloud with a map and compass, or what you are carrying. It does not see the state of the path, river levels, snow and ice already on the ground, or how the forecast is changing during the day. A Good day can still go wrong if you start late, turn an ankle or lose the path in mist, and a Marginal day can be fine for an experienced party on the easiest route.

On any day, carry waterproofs, warm layers, a hat and gloves, food, water, a head torch and a charged phone, and know how you would navigate if the top is in cloud. Tell someone your route and when you expect to be down. In winter conditions you need an ice axe and crampons and the skill to use them, or a guide.

Route notes for An Teallach - Sgurr Fiona

Dundonnell via Bidein a' Ghlas Thuill

From Dundonnell (roadside parking). A steep path climbs onto the ridge north of the summits, then a rocky walk over Bidein a' Ghlas Thuill to Sgurr Fiona. Graded Hard: steeper, rougher or longer than the moderate routes, with more time on high, exposed ground. About 4h 40m there and back by Naismith's rule (6.8 km one way, 1,154 m of ascent).

Full traverse from Corrie Hallie

From Corrie Hallie car park. A long day over the whole ridge, crossing the exposed pinnacles of Corrag Bhuidhe and Lord Berkeley's Seat. Graded Scramble: hands-on rock. Wind and wet rock make a scramble far more serious than its grade, so it is the first route to drop on a Marginal or Poor day. About 5h 30m there and back by Naismith's rule (8.9 km one way, 1,181 m of ascent). Today's summit gusts of 51 mph are a reason to choose a walking route instead.

In an emergency

Call 999, ask for the police and then mountain rescue. Mountain rescue teams in the UK are volunteers called out through the police. Give your location (a grid reference from a map or phone app if you can), what has happened, how many are in your group and your phone number, then keep the phone free. If you have no signal, try to move to higher ground or text 999; you need to have registered your phone with the emergencySMS service before for a text to work.
