የSt. Moritz (St Moritz) አየር ሁኔታ ወር በወር

St Moritz-forum threads on January describe genuinely deep cold as the norm, readings capable of dropping well below minus 20 on the coldest nights, though posters are consistent the resort's famously dry, sunny air makes the cold feel more bearable than the raw number suggests, a contrast regulars call the area's own champagne climate. Snow coverage is variable year to year, sometimes plentiful early, other years not building a real base until later, closer to March. Skating and other activities on the frozen lake itself typically don't start until the very end of January. Everything from restaurants to lift access runs at full capacity this time of year regardless of snow totals. Regulars recommend serious cold-weather layers rather than standard ski gear alone, given how far below freezing conditions typically run. The record: a frigid -3.1C by day dropping to -13.5C at night, a notably high 88.8cm of fresh snowfall and 77 percent humidity.

St. Moritz's forum calls February peak ski season proper — dry, crisp conditions, with reliable snow through the Engadine and sunnier days as the month goes on. Regulars' practical warning: book well ahead if you want a hotel for just one night, single-night stays are hard to find during the busiest weeks.

March is the month the St Moritz forum recommends over February: longer days, more sun, and noticeably fewer people. The shape of a March day is the useful part - the morning is the skiing, on runs groomed overnight and still firm, while by afternoon the sun has softened the snow and the sensible plan is a mountain restaurant and the terrace. Late in the month the Corvatsch side holds its snow better than Corviglia, being less sun-exposed. Nights still drop hard whatever the afternoon did, so layers rather than one jacket. The record: 1.8C days, -9.5C nights, 71.6cm of snow, 12.5 precipitation days and 9.2 hours of sun.

St. Moritz-forum threads on an April visit describe Corviglia's lifts as typically closing early to mid-month, posters naming an early Easter as the reason some years see most cable cars staying open only to around the eighth. Regulars call late-April visits still genuinely workable, several posters naming restaurants and some cable cars as still running even after the main lifts close. Posters call April weather genuinely unpredictable, several regulars describing bright sun and blue sky flipping to snow or rain within an hour. Regulars call most hotels genuinely closed for the off-season by this point, several threads naming a handful that stay open through the full stretch as the real exceptions. Posters recommend confirming which lifts and hotels are actually operating before an April trip, several regulars calling this standard given how much the shoulder season varies year to year. The record: 5.4C days, -4.3C nights, 105.5mm across nearly 15 days and 79 percent humidity.

St Moritz-forum threads on a May visit call this a quiet shoulder season, posters describing many businesses closed for the transition between winter and summer with only a handful of mountain cable cars still running. Regulars call mid-May weather capable of feeling almost warm and sunny during the day while turning cold at night, a real chance of a passing storm or even a late snow shower. Posters call several Michelin-listed restaurants closed this month, though regulars insist plenty of solid dining options remain open regardless. Regulars recommend confirming that accommodation includes the complimentary local transport and cable car pass, a real value add during the quieter shoulder weeks. Posters call May still worth the trip for anyone prioritizing quiet over full activity access, considerably fewer visitors than peak season. The record: 9.8C days feeling like 8C, 0.5C nights, an extraordinarily high 155.5mm across nearly 22 days and 75 percent humidity.

St Moritz-forum threads on early June describe on-piste skiing as effectively over except on the high glacier runs above roughly 2500 meters, posters calling the valley floor already firmly in summer mode. Regulars call a late snowfall still entirely possible this early in June despite generally mild conditions, a passing system capable of dusting the peaks after weeks of clear weather. Posters describe the long daylight hours as a real upside, hiking and lake activities filling the gap left by the closed lower lifts. Regulars recommend checking current glacier lift status rather than assuming last year's schedule repeats. Posters call real layers sensible for the evening chill, mornings turning noticeably brisk despite warm afternoons. Regulars call June a genuinely quiet, scenic window for anyone not chasing the ski season specifically. The record: 15.7C days feeling like 16C, 4.5C nights, an extraordinarily high 172.5mm across nearly 20 days and 81 percent humidity.

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.

St Moritz-forum threads on September weather describe conditions as generally stable, comfortably mild rather than intense during the day and already genuinely cool once shadows fall. Posters call the sun-versus-shade contrast dramatic here, a sunny spot feeling noticeably warmer than a shaded one at the same reading. Regulars describe real day-to-day variability, one visitor reporting a warm start followed by a properly wet, cold stretch with a fresh dusting visible on surrounding peaks by day four. Posters call actual accumulation in town genuinely unlikely, though higher elevations nearby can see a real dusting with little warning. Regulars recommend dressing in layers that can come on and off through the day. Posters call the Engadin lakes and mountain scenery worth the trip regardless of conditions. The record: 12.9C days feeling like 12C, 2.7C nights, an extraordinarily high 120mm across 15 days, a notably high 19.7cm of fresh accumulation and 84 percent humidity.
