Is it safe to climb High Street today?

Poor Today Monday 19 October

• Wind and gusts: Summit wind up to 41 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: 28% chance of rain, about 4 mm in all.
• Cloud: Cloud cover averages 68% and humidity 94% at summit height. The forecast gives no cloud base height; the main peak page estimates one from the valley forecast.
• Temperature and wind chill: Up to 8°C at the summit, down to 2°C, feeling as cold as -2°C in the wind.
• Daylight: Sunrise 07:48, sunset 18:04: 10h 17m of daylight. The longest route listed here takes about 3h 5m there and back by Naismith's rule, before stops.

Is it safe to climb High Street tomorrow?

Marginal Tomorrow Tuesday 20 October

• Wind and gusts: Summit wind up to 30 mph, gusting 37 mph. That is past the Marginal line (wind 25 mph or gusts 45 mph): expect to be pushed about on ridges and the summit.
• Rain: 84% chance of rain, about 11.3 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 100% and humidity 97% 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 7°C at the summit, down to 3°C, feeling as cold as 2°C in the wind.
• Daylight: Sunrise 07:49, sunset 18:02: 10h 13m of daylight. The longest route listed here takes about 3h 5m 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.

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.
