Summary for all mountain areas

A fine day for most places with light winds. Patchy cloud around some hill slopes early in the day will lift to leave many summits clear, but cloud banks are likely to persist on west coastal tops in Scotland, a little drizzle here in the morning, breezier too in the far northwest.

How windy? (On the Munros)

Westerly 5 to 15mph, strongest over tops in north Lochaber in the morning.

Cloud banks in the morning covering many tops in Lochaber and near coasts elsewhere above 800m, some lower patches for a time. Bases tending to rise during day mostly above 1000m and breaks forming toward tops best inland.

Chance of cloud free Munros?

Planning Outlook

A fine start to the week with high pressure nearby, but easterly breezes will tend to strengthe. Most places dry through Monday and Tuesday, but generally deteriorating from the south into midweek as low pressure moves in from the south, patchy rain will increasingly spread northward with some local stronger wind. Broadly unsettled as next weekend approaches with bands of heavy rain forming mixed with showery bursts at times, but fairly warm and somewhat humid. Wind speed and direction likely to vary considerably day-to-day.
