Planning Outlook

All mountain areas of Britain from Saturday 2nd July 2016

Westerly winds will predominate over the next week or so. These will bring in relatively chilly conditions, and at some stage most days rain. Often the rain will amount only to showers, but from time to time a few hours of persistent rain will come in. Most rain (and accompanying low cloud) will be on western mountains (little to choose between NW Scotland and W Wales), whilst driest areas will be toward the east. Winds mostly fairly light, occasional windy days.
