Effect of the wind on you?
Expect arduous walking conditions on the hills throughout the day, sometimes difficult on tops. Notable wind chill.

40%
Sunshine and air clarity?
Generally cloudy and murky in rain, but as rain breaks up, patchy sunshine coming through and visibility becoming very good.

8 to 10C, but tending to lower through day, perhaps 6C later afternoon.
Freezing Level
Above the summits
Planning Outlook
High pressure will drift southwards and southwesterly winds will strengthen across Britain in the first half of the week, soonest across Scotland. Staying windy through into next weekend, gales or sometimes severe gales on higher mountains, particularly Scotland. Rain will become frequent in western Scotland as fronts come in from the Atlantic. Spells of rain elsewhere - less wet for Wales and southern Pennines, although a risk of heavier rain moving further south by the weekend. Temperatures will vary through the next 10 days, sometimes fairly warm and humid, but chiller air spreading from the northwest at times - Scottish high tops occasionally near freezing point.
