The day on the hill

A fine day on Meall na Teanga: 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 easterly, with gusts of 10–20 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 mid-morning. The cloud base could be as low as 700–1000 m mid-morning. Good spells of sunshine are likely. 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 0 to 4°C, feeling like -4 to 0°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 4:30pm, 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

The surrounding model grid indicates 7.2 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

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.

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 psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. 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 Meall na Teanga, though expect cloud coming and going on the summit.

Wind

On the summit expect a south-easterly wind of 10–20 mph for most of the day, with gusts of 20–30 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 mph.

Cloud and visibility

The tops are likely to drift in and out of cloud, with the best chance of a clear summit around midday. The cloud base could be as low as 700–1000 m mid-afternoon. In cloud you'll be finding your way without landmarks, so carry navigation you trust and know how to use, with a backup such as a spare battery or a map and compass.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around 0 to 4°C, feeling like -4 to 0°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 4:25pm, 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.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 2.1 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

A mixed night to camp, mainly because of damp air. Light winds on open ground, gusting no more than about 25 mph. It should stay dry. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 1°C around 900 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.

Generic exposed-rock guidance

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. Cloud on the tops may make route-finding and retreat harder. The rock around the summit is mostly psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Psammite is a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. 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.

Overnight · Aurora, stars & meteorsAfter darkBetaAurora activity could be sufficient, but cloud is forecast to block the northern view View forecastClose forecast

After dark: aurora and stargazing

Night beginning 2026-11-06. All times are UK local time.

Aurora activity could be sufficient, but cloud is forecast to block the northern view

Aurora could come within view from here, most likely low towards the northern horizon. Activity peaks around Kp 5.0 (on a 0 to 9 scale). NOAA has a G1 storm watch out for this date, though the timing of the strongest activity can shift.

Look north-north-west, low above the horizon. A clear, open view that way matters more than height.

The Moon is below the horizon around the best forecast hour, so moonlight should not wash out a faint display then.

Aurora viewing guidance

Cloud is forecast to block most of the northern view, so seeing aurora is unlikely.

The terrain horizon has not been checked at this exact location. Nearby slopes or a lower campsite can have a very different view.

Relatively little surrounding artificial light lies towards the aurora compared with other assessed peaks.

Most likely a faint glow low in the sky that a phone camera shows better than your eyes. It can look like thin cloud.

Not sure what you are seeing? Take a Night-mode photo facing north: rest the phone on a rock or pack, use the main lens and a timer, and hold still for a 3–10 second exposure. Cameras show aurora colour long before eyes do.

Aurora activity can change quickly. This is experimental guidance, not a guaranteed sighting. Check again before heading out.

Stargazing

Poor sky conditions during the best available spell: 6 Nov, 19:00 GMT to 20:00 GMT.

Mostly cloudy, so little chance of seeing the stars. Hazy, which dims the fainter stars.

Moon-free dark sky: 6 Nov, 18:35 GMT to 7 Nov, 05:30 GMT.

The day on the hill

A mixed day on Meall na Teanga, with cloud coming and going on the summit.

Wind

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

Cloud and visibility

Expect the summit to be in cloud for most of the day. The cloud base could be as low as 600–900 m mid-afternoon. In cloud you'll be finding your way without landmarks, so carry navigation you trust and know how to use, with a backup such as a spare battery or a map and compass. Mist or fog is possible in the valleys during the morning, clearing by about 9am.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around -2 to 2°C, feeling like -4 to 0°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 4:25pm, 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. It's still three days off and could change, so check again nearer the time.

A mixed night to camp, mainly because of damp air. Light winds on open ground, gusting no more than about 15 mph. It should stay dry. Above about 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. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 1°C around 900 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.

The day on the hill

A mixed day on Meall na Teanga, with cloud coming and going on the summit.

Wind

On the summit expect light winds of up to 15 mph, mainly westerly, with gusts of 15–25 mph at the windiest. Lower down on the open hillside the wind will be light, under 10 mph.

Cloud and visibility

Expect the summit to be in cloud for most of the day. The cloud base could be as low as 500–800 m mid-afternoon. In cloud you'll be finding your way without landmarks, so carry navigation you trust and know how to use, with a backup such as a spare battery or a map and compass. Mist or fog is possible in the valleys early on, clearing by about 4am.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around -2 to 2°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 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 heights are particularly hard to pin down today. It's still five days off and could change, so check again nearer the time.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 7.6 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Night beginning Monday 9 November 2026

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. The wind swings from westerly to northerly overnight, so a pitch sheltered at dusk may not be by morning. It should stay dry. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A frost up around 900 m, down to about -2°C. 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.

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

Fair conditions for exposed scrambling. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Cloud on the tops may make route-finding and retreat harder. The rock around the summit is mostly psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. 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 fine day on Meall na Teanga: dry, with light winds.

Wind

On the summit expect light winds of up to 15 mph, mainly north-easterly, with gusts of 10–20 mph at the windiest. Lower down on the open hillside the wind will be light, under 5 mph.

Cloud and visibility

Any early cloud on the tops should clear soon after dawn. 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. Mist or fog is possible in the valleys early on, clearing by about 9am. Good spells of sunshine are likely.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around -2 to 2°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 4:15pm, 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.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 2.4 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Night beginning Wednesday 11 November 2026

Full overnight outlook

A mixed night to camp, mainly because of damp air. Gusts reach about 25 mph on open ground, so peg out well and use the guylines. Look for shelter from the southwest. It should stay dry. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. The air is damp up around 900 m, so expect heavy condensation. Leave the vents open. A frost up around 900 m, down to about -2°C. 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.

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.

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. The rock should be mostly dry, though drainage lines and shaded holds may still be damp. Cloud on the tops may make route-finding and retreat harder. The rock around the summit is mostly psammite, a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Psammite is a hard, sandy rock that has been squeezed and heated. It grips well when dry and is fair when wet. It is generally solid and blocky. 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.
