Været i El Calafate (Perito Moreno) i desember

December is Patagonian summer — among the least cold months of the year here — but the forum is unanimous that temperature is not what makes Torres del Paine hard. Summer is the windiest season, and one trip report describes four consecutive days delivering clear sky and high sun, 80mph winds, snow, hail and rain. The averages shown here read cold and snowy even in December because they cover exposed high terrain rather than only the valley trails, and that is the honest picture: it is the wind that makes you cold. Regulars pack a fleece hat or Buff for exactly that, note most campgrounds sit somewhat sheltered, and reckon the exposed sections feel far worse than the actual risk. The days are very long.

El Calafate-forum threads on a July visit describe this as genuinely not the ideal time for glacier trekking, posters naming HieloyAventura as the sole concessionaire and warning winter can limit trekking options. Regulars call the boat-plus-walkway viewing of Perito Moreno genuinely still doable same-day regardless of season, several posters naming this the reliable fallback when trekking isn't practical. Posters call real layered, waterproof outer clothing standard winter advice, several regulars naming this essential given how cold and exposed the glacier viewpoints get. Regulars call bus schedules genuinely variable by day of week and season, several threads recommending checking current timetables before a July day trip. Posters recommend confirming trekking availability directly with the operator, several regulars calling this standard given how much winter affects access. The record: 5.8C days, -3.1C nights, 60.9mm across nearly 10 days and 87 percent humidity.

El Calafate-forum threads on a June visit describe this as genuinely workable despite being deep winter, posters calling cold, wind and short daylight real factors though most hotels and excursions keep running on a lighter schedule. Regulars call the Perito Moreno glacier open year-round, tours available and considerably less crowded in June than during the summer peak. Posters call ice trekking on the glacier itself unavailable this month, boardwalk viewing by bus the realistic way to see it in June instead. Regulars call El Chalten a solid day trip from El Calafate, roughly three to three and a half hours each way with real hiking trails right from the tiny town. Posters recommend real flexibility around June bookings, some excursions here genuinely prone to weather cancellation this time of year. The record: 6.2C days feeling like 4C, -2.3C nights, 46.2mm across nearly 10 days and 68 percent humidity.

El Calafate-forum threads on end-of-May conditions describe the Perito Moreno glacier as still accessible, posters calling the standard viewing platforms and boardwalks open regardless of season though ice-trekking day trips can become unavailable this late in fall. Regulars call the weather itself genuinely cold and often wet, real waterproof layers, a warm hat and proper gloves all standing advice for a day at the viewpoints. Posters recommend checking current tour availability directly given some operators scaling back as the season winds down. Regulars describe El Calafate town as considerably quieter this time of year, restaurants and shops still open but with far fewer visitors than the summer peak. Posters call proper winter boots essential for the boardwalk sections, ice and wet timber real hazards underfoot. Regulars recommend real flexibility in any itinerary here. The record: 9C days feeling like 7C, -0.1C nights, 55.6mm across nearly 12 days and 86 percent humidity.

El Calafate-forum threads comparing March against April are fairly consistent March carries slightly better odds against an early system, though posters call April a genuinely solid pick for the Perito Moreno glacier boardwalks. Regulars describe conditions as chilly by day and properly cold once the sun drops, real winds a standing feature regardless of date. Posters call the wider Patagonia region reliably windy through the month, gear rated for real gusts worth prioritizing over pure warmth. Regulars say nearby El Chalten sees an earlier chance of accumulation, worth checking current conditions before a hiking-heavy itinerary there. Posters call clear skies genuinely common through April despite the cold, strong visibility of the glacier a real upside of the shoulder season. Regulars recommend real layers regardless of how the morning starts. The record: 13.2C days feeling like 10C, 2C nights, a notably high 6.3cm of fresh accumulation and 80 percent humidity.
