Argyll and Loch Lomond
A good day in Argyll and Loch Lomond: dry and breezy.
Sunshine and sky
Sunshine through the day. The time blocks show where the model places the brighter spells.
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.
High-ground wind (900 m)
At around 900 m, expect a south-westerly wind of 15–25 mph, gusting 20–30 mph. A wind like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Walking impact
A steady wind of 15–25 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Rain and showers
It should stay dry.
Cloud-free summits
Clear-summit estimate: about 75% early, about 55% around midday and about 80% later.
Cloud and visibility
The tops should stay mostly clear of cloud. Mist or fog is possible in some valleys early on. Good spells of sunshine are likely.
Temperature and wind chill
At around 900 m it will be 4 to 8°C, feeling like -2 to 2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.
Freezing level
The freezing level is close to summit height.
Daylight
Sunrise 08:01, Sunset 18:05, about 10.1 hours daylight.

Full regional overnight outlook
Too windy for an exposed pitch up around 900 m on some hills. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 40 mph around 900 m and nearer 30 mph around 300 m, which makes for a noisy, testing night even in a good tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. A little 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. The air is damp down around 300 m, so expect heavy condensation. Leave the vents open. 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 good (87/100). Rock is likely to be mostly dry, though local seepage and shaded holds remain unresolved. Mapped summit-point geology across the representative hills includes psammite, pelite or semipelite, volcanic rock and granite, gneiss or gabbro. Rock can therefore respond differently to moisture between crags and routes.
Representative summit-point samples across the region; individual crags and routes may differ.

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.
