Snake Pass by Motorcycle: Weather Hazards on England's Iconic Bikers' Road

Snake Pass is the kind of road that motorcyclists talk about in hushed reverence — and nervous caution in equal measure. The A57 between Glossop and Sheffield is approximately 28 km of moorland switchbacks, exposed summits and damp tarmac that rewards riders who respect it and punishes those who don't. It climbs to around 510 metres at the Snake Pass summit, enough altitude to create weather conditions completely detached from what you'll feel in either valley.

This is a legendarily beautiful road. It is also one of the most frequently closed roads in England.

Route Overview

The A57 Snake Pass carves through the heart of the Peak District National Park, linking the Greater Manchester commuter town of Glossop to the western edge of Sheffield. There are no petrol stations on the pass itself. There is no shelter. There are almost no other roads — if conditions close the pass, you turn back.

Distance: ~28 km (Glossop to Sheffield via A57)
Summit elevation: approximately 510 m
National Park: Peak District
Key hazard period: November through March (frequent closures), ice risk extending into April

The appeal is obvious: tight curves, open moorland views, and a genuine sense of remoteness just 30 minutes from two major English cities. The hazards are equally obvious once you understand the weather patterns at play.

Weather Patterns by Section

Western Approach: Glossop Side

The western flank of Snake Pass faces the prevailing Atlantic weather systems tracking in from the Irish Sea and across the Pennines. This side is noticeably wetter and cloudier than the Sheffield side, with maritime air masses regularly bringing low cloud, drizzle and poor visibility even when the east of England is enjoying dry weather. Cloud base frequently sits at or below summit height, meaning you can ride into fog within minutes of leaving Glossop.

Rainfall on this side is persistent rather than dramatic. The road surface stays damp for hours after rain has stopped — a critical factor for grip on the hairpin bends.

Summit Area

The summit plateau is where Snake Pass earns its reputation. Exposed moorland with no natural windbreaks means wind speeds increase significantly compared to the valleys below. What feels like a moderate breeze in Sheffield or Glossop can be a genuine gale at the summit, with gusts that push a fully-loaded motorcycle sideways with little warning.

Temperature drops sharply with altitude. A rule of thumb: subtract 1.5°C for every 100 metres of climb. If it's 10°C in Glossop, expect 7–8°C at the summit — and that calculation doesn't account for wind chill, which can make felt temperatures brutally cold even on days that seem mild from below.

Eastern Descent: Sheffield Side

The Sheffield-facing slopes are marginally drier on average, sitting in the partial rain shadow of the Pennine ridge. However, ice lingers significantly longer on the eastern side in winter and early spring. Shadowed corners — and there are many on the descent — receive no direct sunlight until late morning at best in winter months. Ice that has melted on the exposed sections can persist in these shadows well into the afternoon.

Key Weather Risks for Motorcyclists

Ice and snow — Snake Pass is one of the most frequently closed roads in England. Closures from November through March are routine. The pass has been shut for days at a time following snowfall, and even a light frost can create black ice on the steep descents. Ice can persist well into April in shaded sections, particularly on the eastern hairpins.
Freezing fog — The summit sits at precisely the altitude where supercooled fog forms with very little warning. Visibility can drop to 20 metres or less within seconds. At any meaningful road speed, this is genuinely life-threatening. This fog is not always visible from the valleys below.
Crosswinds — The open moorland provides no protection from lateral gusts. During Atlantic storm systems, gusts can exceed 60 mph (nearly 100 km/h). Crosswinds hit hardest on the more exposed western approach and the open summit section. Larger windscreen fairings become a liability in these conditions.
Sudden temperature drops — Valley temperatures are meaningless for planning your clothing. Check the summit forecast specifically. An 8°C difference between Glossop and the Snake Pass summit is not unusual — enough to make the difference between comfortable riding and hypothermia risk on a long day out.
Wet roads year-round — The Snake Pass area receives over 1,400 mm of rain annually, roughly double the UK average and far above Sheffield or Manchester city centre figures. The road surface stays damp for extended periods, and patches of mud or debris washed across the carriageway are common after heavy rainfall.

Best Time to Ride

June, July and August offer the most reliable conditions for Snake Pass. Summer brings warmer temperatures, longer daylight and the lowest probability of ice. Even then, the Pennines create their own microclimate — a summer morning can be foggy and cold at the summit while the valleys are warm and clear.

May and September are viable with careful forecast checking. October marks the beginning of the genuinely high-risk period: the first frosts can appear at summit height while the valleys remain frost-free.

November through March: only attempt Snake Pass if you have verified conditions are clear, not just "probably fine." The road authority closes it when conditions deteriorate — check before you leave.

Tips for Riding Snake Pass Safely

Check Traffic England before every ride. The pass closure status is updated in near real-time. A closed Snake Pass is not an inconvenience — it is a serious weather event.
Use the Met Office Mountain Forecast, not just the local forecast for Sheffield or Manchester. These are fundamentally different weather pictures.
Never attempt in freezing fog. If forecast shows fog with temperatures near or below 0°C at 500 m, postpone the ride.
Carry high-visibility gear and wear it. Visibility can drop to 20 metres in summit fog. Being seen is not optional.
There is no fuel or shelter on the pass. Arrive with a full tank and plan your clothing for the coldest conditions you might realistically encounter at the top.
Ride the hairpins slowly regardless of conditions. The tight bends on both approaches catch out experienced riders every season. Damp patches, gravel washed from the verges and unexpected camber changes are a constant feature of the road.
Allow time for the eastern descent in winter. Don't rush the Sheffield-side hairpins even if the summit seems clear. The shadowed corners hold ice long after the exposed sections have dried.
Check Route Forecast's elevation profile overlaid with weather to see where temperature drops and wind picks up as the road climbs through those final kilometres to the 510m summit — even an 8°C swing between Glossop and the top is immediately visible on the profile. Export the forecast as an image and share it with your riding group on WhatsApp so everyone is starting the day with the same picture of summit conditions.

Before you head out, use Route Forecast to check the point-by-point weather forecast for the entire route. Wind, rain and temperature at every kilometre, in real time — overlaid on the full elevation profile so you see exactly where weather changes meet each climb and descent. Export the forecast as an image to share with your group before departure.
