The day on the hill

A fine day on Birks: dry, with light winds and clear tops for most of the day.

Wind

On the summit expect light winds of up to 15 mph, mainly south-easterly, with gusts of 10–20 mph at the windiest.

Cloud and visibility

The tops should stay mostly clear of cloud. A few forecast models bring the cloud base down to around 500–800 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Patchy mist is possible in sheltered valleys early on.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around 2 to 6°C, feeling like -2 to 2°C in the wind. The freezing level is above the summits. Take a hat, gloves, a windproof and a spare warm layer.

Daylight

A short day, with only about 9 hours of daylight. Sunset is around 4:20pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

Cloud height is hard to pin down, so the summit could be in or out of cloud at short notice. Things could still change through the day, so keep an eye on the sky.

Sunshine context Model-grid estimate, not summit sunshine

Full overnight outlook

A mixed night to camp, mainly because of damp air. Light winds on open ground, gusting no more than about 20 mph. It should stay dry. The air is damp at every height we checked (300-600 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 3°C around 600 m. A warm 3-season or 3–4 season bag rated to about 0°C comfort, and a warm mat, should do. Allow more if you sleep cold.

Warmth planning: As a broad starting point, consider a warm 3-season or 3–4 season bag with an ISO/EN comfort rating at or below about 0°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Excellent conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. The rock around the summit is mostly volcanic tuff, rock formed from compacted volcanic ash and debris. It is rough and grippy when dry and usually still grips reasonably when wet. It is mostly solid, in slabs and ledges, though weathered patches can be crumbly. On the usual routes up you may also cross rhyolite, which grips well when dry and gets slippery on smoother faces when wet. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Volcanic tuff is rock formed from compacted volcanic ash and debris. It is rough and grippy when dry and usually still grips reasonably when wet. It is mostly solid, in slabs and ledges, though weathered patches can be crumbly. These are general notes for each rock type, from geological map samples at and around the summit. The rock on your line can differ, and lichen, vegetation and seepage all change how it feels underfoot.

The day on the hill

A fine day on Birks: dry, with light winds and clear tops for most of the day.

Wind

On the summit expect light winds of up to 10 mph, mainly easterly, with gusts of 5–15 mph at the windiest.

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of a clear summit around midday. A few forecast models bring the cloud base down to around 400–700 m at times. The cloud base sits close to summit height, so the top could go in and out of cloud at short notice. Good spells of sunshine are likely.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -2 to 2°C in the wind. The freezing level is above the summits. Take a hat, gloves, a windproof and a spare warm layer.

Daylight

A short day, with only about 9 hours of daylight. Sunset is around 4:15pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

Cloud height is hard to pin down, so the summit could be in or out of cloud at short notice. Some of the detail could still change, so have a last look at the forecast in the morning before you set off.

The day on the hill

A good day on Birks: dry and breezy, with clear tops for most of the day.

Wind

On the summit expect a northerly wind of 15–30 mph for most of the day, with gusts of 30–40 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.

Cloud and visibility

The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out. The air should be clear, so expect far-reaching views as long as the tops stay clear.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around -4 to 0°C, feeling like -12 to -8°C in the wind. The freezing level is around 200–500 m, so it will be below freezing on the tops. Take a hat, gloves, a windproof and a spare warm layer.

Daylight

A short day, with only about 9 hours of daylight. Sunset is around 4:15pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

There is some disagreement between forecast models on wind strength. It's still two days off and could change, so check again nearer the time.

Full overnight outlook

A mixed night to camp, mainly because of the cold. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the west. Dry to pitch, then a little rain overnight, easing by morning, though the tent may still be wet. A cold night, down to about 2°C around 600 m. A warm 3-season or 3–4 season bag rated to about 0°C comfort, and a warm mat, should do. Allow more if you sleep cold.

Warmth planning: As a broad starting point, consider a warm 3-season or 3–4 season bag with an ISO/EN comfort rating at or below about 0°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Full climbing & scrambling outlook

Good conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. The rock around the summit is mostly volcanic tuff, rock formed from compacted volcanic ash and debris. It is rough and grippy when dry and usually still grips reasonably when wet. It is mostly solid, in slabs and ledges, though weathered patches can be crumbly. On the usual routes up you may also cross rhyolite, which grips well when dry and gets slippery on smoother faces when wet. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

The day on the hill

A good day on Birks: breezy, with clear tops for most of the day.

Wind

On the summit expect a south-westerly wind of 15–30 mph for most of the day, with gusts of 25–35 mph at the windiest. Lower down on the open hillside it will be more like 5–15 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.

Cloud and visibility

The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out. The air should be clear, so expect far-reaching views as long as the tops stay clear.

Rain and ground

A little rain at times.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -6 to -2°C in the wind. The freezing level is above the summits. Take a hat, gloves, a windproof and a spare warm layer.

Daylight

A short day, with only about 9 hours of daylight. Sunset is around 4:10pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

The forecast models disagree on how strong the wind will be, so it could be noticeably stronger than this. Cloud heights are particularly hard to pin down today. It's still four days off and could change, so check again nearer the time.

Full overnight outlook

Too windy for an exposed pitch up around 600 m. Lower down, a poor night to camp on open ground. Gusts reach about 40 mph on open ground, which makes for a noisy, testing night even in a good tent. Pitch low down and in real shelter, or leave it for another night. Expect a wet night, around 12 mm of rain, with rain while you pitch and still falling when you pack up. Up around 600 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. Overnight lows of about 4°C at 600 m. A 3-season bag rated to about 2°C comfort, and a warm mat, should do. Allow more if you sleep cold.

The day on the hill

A poor day on the tops of Birks, with very strong, gusty winds and burns likely to be in spate.

Things to watch

Burns and rivers are likely to be in spate through the day and overnight, so unbridged crossings could be difficult or impossible. Timings are rough. Turn back if a crossing looks unsafe.

Wind

On the summit expect a south-westerly wind of around 25–35 mph first thing, rising to 40–50 mph by mid-afternoon, with gusts of 55–65 mph at the windiest. Lower down on the open hillside it will be more like 10–20 mph. Gusts like that are strong enough to make walking very difficult and tiring, with a risk of being blown off your feet. Avoid exposed ridges and edges. If the windier forecast models are right, summit gusts could reach 85–95 mph.

Cloud and visibility

The tops are likely to stay mostly clear of cloud, though brief patches cannot be ruled out.

Rain and ground

Rain for much of the day, becoming heavier later. Expect 10–20 mm in total. Some forecast models keep it drier in the morning.

Warmth and kit

On the tops it will be around 6 to 10°C, feeling like 0 to 4°C in the wind. The freezing level is above the summits. A windproof and an extra layer for stops will help. Pack waterproofs too, and keep a warm layer dry in your pack.

Daylight

A short day, with only about 9 hours of daylight. Sunset is around 4:10pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

It's still five days off and could change, so check again nearer the time.

Full overnight outlook

Not a night to camp on the open hill. Gusts reach about 65 mph around 600 m and nearer 55 mph around 300 m, strong enough to flatten or tear a tent. Don't count on finding shelter once you're up there. Choose another night or a low, sheltered spot. The wind swings from southwesterly to westerly overnight, so a pitch sheltered at dusk may not be by morning. Expect a wet night, around 20 mm of rain, mostly early on, so you'll likely pitch in the rain. A cold night, down to about 2°C around 300 m.

It should stay dry. Most forecast models bring some rain, though, so don't count on it staying dry. The ground is very wet after recent rain, so expect boggy paths.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -6 to -2°C in the wind. The freezing level is close to summit height. Take a hat, gloves, a windproof and a spare warm layer.

Daylight

A short day, with only about 8 hours of daylight. Sunset is around 4:10pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

It's still six days off and could change, so check again nearer the time.

Full overnight outlook

A mixed night to camp, mainly because of the rain. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the southwest. The wind swings from southwesterly to southeasterly overnight, so a pitch sheltered at dusk may not be by morning. Dry to pitch, then a wet night, around 11 mm of rain overnight and into the morning, so expect to pack a wet tent. A cold night, down to about 2°C around 300 m. A warm 3-season or 3–4 season bag rated to about -2°C comfort, and a warm mat, should do. Allow more if you sleep cold. The ground will be sodden after recent rain, so pick a firm, well-drained pitch.

Warmth planning: As a broad starting point, consider a warm 3-season or 3–4 season bag with an ISO/EN comfort rating at or below about -2°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

The ground is likely to be very wet after recent rain. Expect boggy approaches and choose a durable pitch carefully.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Good conditions for exposed scrambling. After recent rain the rock may still be wet in places, especially shaded holds and drainage lines. Gusts of 20–30 mph will be noticeable on exposed ridges. The rock around the summit is mostly volcanic tuff, rock formed from compacted volcanic ash and debris. It is rough and grippy when dry and usually still grips reasonably when wet. It is mostly solid, in slabs and ledges, though weathered patches can be crumbly. On the usual routes up you may also cross rhyolite, which grips well when dry and gets slippery on smoother faces when wet. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Volcanic tuff is rock formed from compacted volcanic ash and debris. It is rough and grippy when dry and usually still grips reasonably when wet. It is mostly solid, in slabs and ledges, though weathered patches can be crumbly. These are general notes for each rock type, from geological map samples at and around the summit. The rock on your line can differ, and lichen, vegetation and seepage all change how it feels underfoot.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit

For a day hillwalk, not a complete route-specific checklist. Carry navigation and backup you can use, warm and waterproof layers, suitable footwear, food and water, a headtorch, emergency shelter, first aid and a way to call for help. Snow, ice, technical terrain and overnight trips need additional equipment and skills.
