What matters most

A good day in the Perthshire Highlands, though expect a blustery wind.

These are direct modelled sunshine hours during daylight, not the probability of sunshine. Cloud cover and summit cloud are assessed separately in the forecast above. The regional median prevents one unusually bright or dull summit cell defining the whole area.

Overnight forecast: 17:00–08:00 (UK local time), in Wild camping below.

Morning · 08:00–12:00GoodSummit winds around 15-30 mph. Gusts around 30-40 mph are possible on exposed ground. Gusts this strong can make walking into it hard work, with buffeting on ridges and edges. Some early summit cloud is possible.

Afternoon · 12:00–17:00GoodSummit winds around 15-25 mph. Gusts around 25-35 mph are possible on exposed ground. Summit cloud becomes more persistent later. Rain is forecast on some hills during this period.

Conservative regional grades across representative summits, so one sheltered hill does not overstate the wider area.

01

High-ground wind (900 m)

At around 900 m, expect a south-easterly wind of 20–30 mph, gusting 30–40 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.

02

Walking impact

Gusts of 30–40 mph are strong enough to make walking into it hard work, with buffeting on ridges and edges.

03

Rain and showers

Drizzle sets in during the early afternoon.

04

Cloud-free summits

Clear-summit estimate: about 60% early, about 85% around midday and about 50% later.

05

Cloud and visibility

The tops should stay mostly clear of cloud. The cloud base could be as low as 600–900 m mid-afternoon. It will look largely cloudy overhead, but that cloud should mostly stay above the tops.

06

Temperature and wind chill

At around 900 m it will be 2 to 6°C, feeling like -6 to -2°C in the wind. It turns milder through the day. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

07

Freezing level

The freezing level is close to summit height.

08

Daylight

Sunrise 08:00, Sunset 18:00, about 10.0 hours daylight.

Full regional overnight outlook

Across these hills, a mixed night to camp, mainly because of the wind. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the southeast. About 4 mm of rain is forecast overnight. 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. Overnight lows of about 4°C at 900 m.

Regional climbing & scrambling outlook

A broad guide to dampness and exposed rock across the area, not a forecast for every crag. Lower, sheltered crags and individual rock types may behave differently.

Conditions for exposed scrambling across the area look very poor (9/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Gusts may reach about 35 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite and quartzite. Rock can therefore respond differently to moisture between crags and routes.

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.
