Argyll and Loch Lomond
A good day in Argyll and Loch Lomond: dry, with light winds and clear tops for most of the day.
Sunshine and sky
Less sunshine later. Sunshine is indicated less often later in the day.
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 north-westerly wind of 10–20 mph, gusting 15–25 mph.
Walking impact
Noticeable on exposed ground, but unlikely to impede most walking.
Ground conditions
The ground is likely to be wet after recent rain.
Rain and showers
It should stay dry.
Cloud-free summits
Clear-summit estimate: about 90% early, about 65% around midday and about 90% later.
Cloud and visibility
Cloud on the tops early should lift off them by mid-morning. The cloud base could be as low as 700–1000 m around midday. Mist or fog is possible in some valleys early on. It will look largely cloudy overhead, but that cloud should mostly stay above the tops. The air should be clear, so expect far-reaching views as long as the tops stay clear.
Temperature and wind chill
At around 900 m it will be 0 to 4°C, feeling like -4 to 0°C in the wind. It turns milder through the day. Take a hat, gloves, a windproof and a spare warm layer.
Freezing level
The freezing level is around 1000–1300 m, so it will be below freezing on the tops.
Daylight
Sunrise 07:54, Sunset 18:13, about 10.3 hours daylight.

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 poor (23/100). Some rock may remain damp or incompletely dried, especially in shade and seepage lines. 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.
