Tomorrow | Thursday | Friday

How windy? (On the summits)

Northeast or easterly, ranging from 10mph Snowdon range to 15, perhaps 20mph south of Bala to Barmouth.

Effect of wind on you?

Most negligible

How Wet?

No rain

Cloud on the hills?

Very little if any

Cloud patches above about 700m, mainly morning eastern areas and Carnedd plateau, will tend to break up - although here and there may persist most of the day (whilst perhaps adjacent summits are free of cloud).

Chance of cloud free summits?


Sunshine and air clarity?

Sunshine extensive, although banks of cloud, most widely Carnedd plateau and eastern areas. Visibility excellent higher areas but fog some valleys morning.

How Cold? (at 900m)


Freezing Level

Above the summits, but ground frost many valleys overnight and post-dawn.

Planning Outlook

All mountain areas of Britain from Thursday 15th October 2015

High pressure will dominate the weather for a week to perhaps ten days (England and Wales), bringing long periods of light wind, well broken cloud and excellent visibility to the hills. Rain will be rare. However, now and again, the remnants of a front will drift around the high bringing over a few hours a little light rain here and there, and more widely cloud will shroud higher areas. Highest Scottish summits intermittently near freezing point and at night many valleys will have a slight frost.
