I'd go with Wednesday and Thursday just for the fact you don't need to worry about getting blown over. 50mph winds aren't particularly nice high up and they probably give me more fear than heavy rain or thick low cloud !
Na na. Incorrecto!
Cairngorms are known for their vicious windstorms, the extra elevation gain makes things worse than they would otherwise be. Unless the low pressure if unreasonably deep, there shouldn't be too many conditions in which you can't walk in the Cairngorms. And Alders' like
wow!
Wind bothers some more than others. 20-30 is kind of strong breeze and a bit more. 50-60 is hard to hear in but still possible to walk into. You may find yourself leaning into it. It is tiring to walk into and of course excellent to walk behind. Side-on is a psychological nightmare!
As for possible: the worst you can really function in is 100-120 mph. At that point, you must be crawling between gusts and gusts will have you on all four clinging to the ground. If the gusts are especially vicious you'll risk being blown off your feet, and all these other horror stories. Great fun to try and walk in, though can get extreme. (and really reserved for winter of course). But that's physically the highest I think you can operate in.
Nathan, some cliffs in the Cairngorms are absolutely fricken monumental. The surrounding ranges (Monadhliath, Drumochter, North east) are all pretty much crag-less, though the Cairngorms are something else. A scale that no other mountain range in Scotland parallels, but not everyones cup of tea. It's more a vast-space,-big-hills-and-cliffs idea. Been across Braeriach and it's especially high on the monumental-scale. Probs my favourite hill in the Gorms.
Back to the thread; What I would do is Drumochter first, maybe A' Bhuidheanach Bheag northward to Carn na Caim to try and get the wind at your back. Warning - they are a drag in bad weather (and I always try to find the positives about the hills). Keep the Gorms for the best day, they really repay the good weather, and then do Alder as planned.
