Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
Low confidence for exact shower details Tuesday to Thursday, but high confidence for more settled conditions thereafter.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Strong Sunlight
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.
Mountain weather forecast
Mostly dry, bright and very warm. Chance of the odd heavy shower.

Additional weather information
Met Office Aberdeen meteorologist's view
High UV levels so suitable protection from the sun may be required. Very warm temperatures bring a risk of dehydration and heat stress, especially on long climbs.
Weather
Some early low cloud may affect coastal ranges before clearing away by mid-morning. Mostly dry and very warm through the day with good sunny spells, though chance of the odd shower any time during the day. The chance of an area of more frequent, heavy and thundery showers pushing north in the evening, but uncertainty over the location or extent of any showers.
Chance of cloud-free hill tops
90% or higher.
Low cloud and visibility
Cloud below 300-500m may affect coastal ranges during the morning and again the evening bringing poor visibilities in mist or hill fog. Any of this should burn back to the coast during the majority of the day. Otherwise little to no low cloud and visibilities generally excellent, but falling moderate to poor should any showers pass through.
Mountain weather information
Weather
An area of frequent, heavy and thundery showers may spread north in the morning but uncertainty over the exact location and extent. Then bright spells and chance of further scattered heavy, slow-moving and thundery showers through the afternoon. Showers through the day potentially causing hazardous conditions with hail, lightning and fast flowing surface water. Likely a good bit cooler than Wednesday.
Chance of cloud-free hill tops
50%, lowest chance around coastal ranges.
Maximum wind speed expected
South veering west 10-20mph at height.
Temperature
- At 800m 11 rising to 15 Celsius.
- Glen 15 rising to 20 Celsius.
- Freezing level Well above summits.
Low cloud and visibility
Areas of cloud down to 300-500m will feed in to coastal ranges at times and visibilities falling poor in mist or hill fog. Some of this burning away during the morning, but significant areas lifting to around 600-800m and persisting throughout the day. Visibilities dropping poor in heavy showers passing through.
