Confidence

High for main theme of introduction of fresher conditions over the weekend. Low for thundery shower detail over the weekend. Still warm, but more seasonable conditions into new working week.

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.

Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
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

Warm with some further sunny periods, with these eventually sparking thundery showers in places.

Additional weather information

Meteorologist's view

There is a small possibility of gusts approaching gale force given thunderstorm activity in the area, with some variability in direction shown likely as well as sudden increases in strength.

Weather

Rather cloudy during the early hours, with cloud perhaps thick enough to produce the odd spot of rain on windward ground especially. Becoming mainly fine during the morning, with temperatures and humidity a little reduced compared to previous days, but still potentially difficult walking conditions in eventual sunny spells and periods of high UV. From around the middle of the afternoon there is a risk of heavy and eventually thundery showers developing, more likely in the south with these gusty and with a risk of hail showers, gradually dying away in the evening.

Chance of cloud-free hill tops

30% improving to greater than 90%.

Low cloud and visibility

Some early cloud down to 400 metres on windward ground, with a chance of moderate visibility in intermittent rain, but improving, with cloud lifting clear of summits before lunch. Visibility very good into the afternoon reducing moderate or poor in showers.

Ground conditions

No recent ground conditions report available.
