Mountain weather
Northwest Highlands Mountain weather forecast table
Confidence
High for mostly dry, warm, settled weather much of weekend then for change to unsettled conditions on Sunday night and early next week. Lower confidence for shower detail later on Saturday and on Sunday morning.
This evening forecast
Dry this evening with long sunny then clear periods. Fresh southerly winds on the tops.
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
Mainly dry. Plenty of sunshine. Breezy on the tops.
