Traveller notes on Grindelwald in May
Other months in Grindelwald
Grindelwald's forum calls September usually fantastic, highs around 70°F with sunny stretches and comparatively little rain, though a cold front can still drop temperatures early in the month. Regulars flag frost as typical around 1500m by late September, and note the Jungfraujoch stays cold enough to feel like winter even in warm layers — pack for both T-shirt afternoons in the valley and near-freezing conditions higher up.
