Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High for the general story but lower confidence for the extent of rain or showers over the weekend. High for a change to colder weather early next week.
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.
Mountain weather forecast
Mostly cloudy with scattered showers. Breezy on the tops.
