The day on the hill

A fine day on Box Hill: 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 15–25 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 stay mostly clear of cloud, though brief patches cannot be ruled out.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around 6 to 10°C, feeling like 2 to 6°C in the wind. The freezing level is above the summits. Take a warm layer and a hat for the top.

Daylight

Sunset is around 4:35pm, so allow time to get off the hill before dark, and carry a head torch.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 0 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Good conditions for exposed scrambling. It should stay mostly dry, but a passing shower could leave the rock damp and slippery. The rock around the summit is mostly limestone, a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Limestone is a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. 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.

After dark: aurora and stargazing

Night beginning 2026-11-05. All times are UK local time.

Aurora is unlikely on this night

Too quiet for a likely sighting from here. Activity peaks around Kp 2.7 (on a 0 to 9 scale). It would take about Kp 6.3 for a camera to pick up a glow low in the north, though that is not a hard line. NOAA has a G1 storm watch out for this date, though the timing of the strongest activity can shift.

Activity can change at short notice. Check again on the night.

Stargazing

Mixed sky conditions during the best available spell: 5 Nov, 23:00 GMT to 6 Nov, 00:00 GMT.

Darkness of the surroundings

Estimated darkness rank 960 of 980 assessed peaks (1 is darkest), based on surrounding artificial light in 2021. This is not a measurement of tonight’s sky.

2021 artificial-light baseline, not measured sky brightness or a Bortle class. Changes to lighting, blue-rich LEDs, terrain screening, atmospheric scattering and cloud-reflected light are not resolved. Similar ranks are not meaningfully distinct. Darkness is not a recommendation to climb a summit at night.

The day on the hill

A good day on Box Hill: 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 stay mostly clear of cloud, though brief patches cannot be ruled out.

Rain and ground

It should stay dry.

Warmth and kit

On the tops it will be around 2 to 6°C. It turns milder through the day. The freezing level is above the summits. Take a warm layer and a hat for the top.

Daylight

Sunset is around 4:30pm, so allow time to get off the hill before dark, and carry a head torch.

Forecast confidence

It's still three days off, so check again nearer the time.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 4.1 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.

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. The rock around the summit is mostly limestone, a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Limestone is a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. These are general notes for each rock type, from geological map samples at and around the summit.

The day on the hill

A good day on Box Hill: dry, with light winds and clear tops for most of the day.

Wind

On the summit expect an easterly wind of 10–25 mph for most of the day, with gusts of 20–30 mph at the windiest. Lower down on the open hillside it will be more like 5–15 mph. It gets windier still after dark, with summit gusts of 25–35 mph, so bear that in mind if you will be out late.

Cloud and visibility

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

The day on the hill

A good day on Box Hill, though expect drizzle for much of the day.

Wind

On the summit expect light winds of up to 15 mph, mainly southerly, 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

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

Rain and ground

Drizzle for much of the day, becoming heavier later. Expect 2–5 mm in total. Some forecast models keep it drier in the afternoon.

Warmth and kit

The freezing level is above the summits. Pack waterproofs, and keep a warm layer dry in your pack.

Daylight

Sunset is around 4:25pm, 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 0 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Mixed conditions for exposed scrambling. The rock is likely to be wet and slippery through the day. The rock around the summit is mostly limestone, a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. These are general notes for each rock type, taken from geological maps around the summit, so the rock on your line may differ.

Limestone is a pale sedimentary rock. It grips well where it is rough, but polished limestone is glassy and is very slippery when wet. It is generally solid, though cracked and fissured along its edges. 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.

BGS record

Summit-area sample Calcareous mudstone Fuller's Earth Formation

Mudstone or slate is a soft, fine-grained rock that splits into thin flakes. It has only fair grip even when dry and is slippery when wet. It is often shattered, breaking into loose flakes, scree and poor holds.

The day on the hill

A good day on Box Hill: light winds and clear tops for most of the day.

Wind

On the summit expect a north-easterly wind of 0–20 mph for most of the day, with gusts of 20–30 mph at the windiest. Lower down on the open hillside it will be more like 5–15 mph. It gets windier still after dark, with summit gusts of 25–35 mph, so bear that in mind if you will be out late.

Cloud and visibility

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

Rain and ground

Drizzle for much of the day.

Warmth and kit

On the tops it will be around 6 to 10°C, feeling like 4 to 8°C in the wind. The freezing level is above the summits. Pack waterproofs, and keep a warm layer dry in your pack.
