Het weer in Puerto Natales in december

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.

Puerto Natales-forum threads on an April visit describe this as genuinely the wet, cold transition from summer to winter, posters naming a real average range of three to thirteen degrees alongside rain and wind. Regulars call bus service into Torres del Paine genuinely already reduced by early April, several posters naming this a factor complicating independent travel without a car. Posters call self-guided hiking and full facility access genuinely only assured through April at the latest, several regulars naming this the real cutoff before infrastructure scales back. Regulars call renting a car a real solution for flexibility, several threads naming driving as still manageable despite the weather even as buses thin out. Posters recommend real waterproof, windproof layers for an April trip, several regulars calling this standard given how fast conditions shift. The record: 9.2C days, 3.7C nights, an extraordinarily high 141.1mm across over 17 days and 82 percent humidity.

Puerto Natales-forum threads on a June visit describe this as genuinely winter in Patagonia, posters calling bus connections to and from El Calafate noticeably harder to find. Regulars call boat trips to the Serrano and Balmaceda glaciers a real question mark in June, several posters asking whether the fjord crossing still runs this deep into winter. Posters recommend confirming Bus Sur's current schedule directly for connections to Punta Arenas or El Calafate, June services here considerably reduced from peak season. Regulars call self-driving into Torres del Paine a real alternative to a guided tour for anyone comfortable with winter roads, though conditions there deserve real caution this month. Posters recommend real cold-weather layers regardless of how the town itself feels, wind here a standing factor even when temperatures seem manageable. The record: 3C days feeling like 0C, -1.3C nights, an extraordinarily high 91.8mm across nearly 16 days and 79 percent humidity.

Puerto Natales-forum threads on a March visit to Torres del Paine describe this as genuinely late fall by Patagonian standards, posters calling conditions considerably more unsettled than the January-February peak, real wind and precipitation more likely. Regulars call the payoff worth it though, fewer trekkers on the trails and lower accommodation rates both genuine upsides of the shoulder season. Posters describe the W trek as still fully doable in March, proper layers and a real waterproof shell simply more essential than during peak summer. Regulars recommend checking the forecast daily rather than trusting anything issued days out. Posters call some March days genuinely calm and clear despite the reputation. Regulars recommend Puerto Natales as the base for permits and transport. The record: 12C days feeling like 9C, 6.1C nights, an extraordinarily high 136.7mm across nearly 20 days and 77 percent humidity.

Puerto Natales-forum threads on an early-May visit describe this as sitting well past the summer crowds, mornings generally clearer and afternoons trending cloudier as a real pattern through the day. Posters call accumulation on higher ground entirely possible by May, some years closing the demanding multi-day circuits while shorter waterfall and lookout trails stay accessible without a guide. Regulars describe town as noticeably quieter, a real number of restaurants and shops already closed for the season by this point. Posters recommend real cold-weather layers regardless of how town feels, conditions in the park running considerably harsher than in Puerto Natales proper. Regulars call the autumn colors and thinned-out crowds worth the tradeoff against shortened trekking options. Posters recommend checking current trail status before committing to a route. The record: 6C days feeling like 3C, 1C nights, a notably high 7.3cm of fresh accumulation and 87 percent humidity.
