Traveller notes on Aviemore in September
Other months in Aviemore
Aviemore's forum calls the Cairngorms genuinely fiercer than England's Peaks or Lakes in December — regulars describe conditions swinging from freezing rain to surprisingly pleasant within the same week, and snow is famously unpredictable, with one visitor reporting brilliant snow one year and barely a smattering the next. The only real certainty is short daylight — around eight hours on a good day.

25 Sep – 25 Oct · usuallyAutumn colourThe birch in Rothiemurchus and the larch along the Spey go yellow through October while the pines stay dark behind them. It lasts a fortnight and the first gale ends it.
