Traveller notes on Davos in August

Notes from nearby St. Moritz (33 km away)

Davos doesn't have its own notes for August yet — these are about St. Moritz, close enough to share the season.

Forum posters describe August valley temperatures as pleasant but never genuinely hot - typically 59-68F (15-20C) with strong sun by day and refreshingly cool nights. Posters flag the Maloja wind, a local valley wind that reliably picks up around midday and strengthens through the afternoon, carrying noticeably colder air down from the surrounding glaciers and snowfields even at the height of summer. Given the altitude, posters say it's normal for snow to fall somewhere in the area roughly once a month even in August, though it rarely settles or lasts long down in the valley itself. Standard packing advice from posters: a light rain jacket plus layerable fleeces that can go on for a cable car ride up and come off again lower down.

Other months in Davos

Davos-forum threads on an April visit describe one poster planning a mid-April trip as genuinely unsure whether the resort would still be open, several regulars confirming it typically stays running. Regulars call snowmaking genuinely the reason many slopes keep operating late into April, several posters naming this as reducing dependence on natural snowfall this time of year. Posters call the season historically closing around the twenty-seventh, several regulars naming this the real cutoff to plan around for a late-April trip. Regulars call weather this far into spring genuinely unpredictable regardless of snowmaking, several threads naming this a real factor even with artificial snow keeping trails open. Posters recommend confirming current lift status before an April trip, several regulars calling this standard given how much conditions can still shift this late. The record: 10.3C days, -0.1C nights, an extraordinarily high 98.4mm across over 15 days and 77 percent humidity.

Davos-forum threads on a June visit describe this as genuinely well suited to easy walking, one regular specifically recommending gentle hikes for older visitors or anyone not looking for a demanding route. Regulars call June conditions generally comfortable for outdoor activity, several posters combining a conference or work trip with real hiking time on the side. Posters recommend checking current trail conditions directly before a mid-June hike, higher routes here still capable of holding leftover cover depending on how the winter went. Regulars call the wider Graubunden region worth exploring beyond Davos itself, several day-trip options mentioned repeatedly across June threads. Posters recommend real layers regardless of a sunny valley forecast, June evenings at this elevation turning cool fast once the sun drops. The record: 19.5C days feeling like 19C, 8.4C nights, an extraordinarily high 160.6mm across over 19 days and 76 percent humidity.

Davos-forum threads on summer hiking recommend contacting the tourist office at the train station for current maps and trail conditions, posters calling this standing advice regardless of route. Regulars call the Weissfluhjoch funicular up to the Strela Pass and on to Schatzalp a genuinely rewarding route, real scenery without an especially demanding climb. Posters describe the Madrisa gondola toward Schlappein and back to Klosters as another strong option, the Silvretta range and its glaciers visible for stretches. Regulars call September still within the hiking season, though trails at higher elevation can already be cooler than midsummer. Posters recommend real layers regardless of how the valley feels, conditions at altitude shifting fast. Regulars call checking current conditions before any higher route worthwhile given how fast weather can turn. The record: 15.9C days feeling like 15C, 6.1C nights, an extraordinarily high 129.1mm across over 15 days and 83 percent humidity.

Davos-forum threads asking whether mid-March works for skiing are generally reassuring, posters calling this historically the warmest month with the best all-around conditions, ideally timed early in March rather than during the Easter crowd surge. Regulars call some lower parts of the ski area genuinely at risk of melt by late March, snowmaking equipment running well into April a real backstop. Posters describe a real chance of fresh accumulation even this late, worth packing boots with good grip regardless of forecast. Regulars call hiking trails a mixed bag, icy in shaded or higher spots through the morning and muddy once the day warms. Posters recommend real layers and waterproof footwear. Regulars call early March the sweet spot for avoiding both winter's harshest cold and the holiday crowds. The record: 6.2C days feeling like 3C, -4C nights, a notably high 58.5cm of fresh accumulation and 76 percent humidity.
