How windy? (On the Munros)
Still some uncertainty: Southeasterly 25 to 30mph becoming southwesterly 35 to 45mph in the afternoon. 50mph+ later.
Effect of the wind on you?
Arduous, blustery conditions developing which will affect ease of walking and balance. Further deterioration into evening.
How Wet?
Possibly only patchy light rain
Risk of rain on and off throughout the day, potentially steady rain lasting a few hours, greatest risk southern Cairngorms. But a reasonable chance that rain is only patchy and some areas may escape drier.
Cloud on the hills?
Locally extensive
Cloud extensive on high ground, especially during and after showers. Breaks most likely near the northern corries of Cairngorm.
Chance of cloud free Munros?
30%
Sunshine and air clarity?
Glimpses of sun through high cloud. Visibility very good if dry, reduced to poor if areas of rain develop.
How Cold? (at 900m)
5 or 6C. Feeling sub-zero in the wind, -5C or below if speeds increase.
Freezing Level
Above the summits

How windy? (On the Munros)
Forecast details very uncertain. Southwesterly 45 to 55mph, risk sustained 70mph. Very gusty.
Effect of the wind on you?
Difficult walking conditions will make progress challenging. Very powerful gusts may easily blow you over. Significant wind chill.
How Wet?
Little or no rain
Probably substantially dry, particularly toward Deeside & Lecht, but risk of rain encroaching from the west occasionally throughout the day, mainly onto hills near the A9, may be only spots in the wind.
Cloud on the hills?
Probably clearing, best east
Patchy cloud on high ground will likely lift and clear into the afternoon. Should rain occur, cloud will become widespread over higher slopes, locally lowering to the mid-slopes near/west of the A9.
Chance of cloud free Munros?
60%
Sunshine and air clarity?
Patchy sunshine through high cloud. Excellent visibility.
How Cold? (at 900m)
8C. Feeling around -5C in the wind.
Freezing Level
Well above the summits.
Planning Outlook
An ongoing unsettled outlook generally dominated by low pressure. Extensive rain and gales into midweek, likely wettest on west-coastal regions. Areas of rain and showers frequently in the forecast later in the week. Temperatures near-average, but feeling cool when exposed to wind. A chillier northwesterly may emerge by next weekend, briefly dropping near freezing on highest Scottish tops. Indications then favour higher pressure at least briefly expanding northwards early next week for some drier days, but unlikely to settle down for long.
