Weather & What to bring

Bariloche has a cool temperate climate with dry summers and falls, pleasant and often windy springs, and snowy/rainy winters. Generally speaking, the summer season (mid-December to early March) is characterized by long stretches of sunny warm weather, with pleasant afternoons and cooler evenings. Fall brings cooler temperatures during nights and mornings with warmer afternoons in March and April, then rainier weather in June.
By mid-May the first snow falls in the mountains, and winter lasts until early September, sometimes even October. Winter is cooler with snow covering the mountains for months, but with only occasional snow fall in town. Spring is variable; with a temperate climate and many warm days, but also with the occasional late season snowstorm touching down on the mountains in October.

During the summer, daylight extends from 5am to 10pm while in winter; daylight is from 9am to 6pm.
