Mountain hazards

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

A very hot and humid day with plenty of sunshine, Southeasterly winds fresh at times.

Additional weather information

Meteorologist's view

On a very hot day preparations should consider adequate water and shade for any hikes, with a strong UV factor and risk of heat stroke on strenuous hikes.

Weather

Another sunny and hot day, humidity is also expected to be high which increasing the risk of heatstroke and dehydration, light southeasterly winds will freshen in the afternoon. Continuing warm and dry in the evening, perhaps some cloud bubbling up towards midnight.

Chance of cloud-free hill tops

95% very little cloud expected below 800m

Low cloud and visibility
