When the Expeditions End: The Mountain Rebuilds Itself
Every year, between late March and April, a profound silence descends over the high slopes. The vehicles roll back toward Copiapó, and climbers pack away their gear. Consequently, the highest active volcano in the world is left entirely alone. For many, this marks the off-season. However, understanding an Ojos del Salado winter is absolutely vital. In fact, for any serious mountaineer, this is where the ascent strategy truly begins.
The Mountain Never Sleeps
Between May and October, the Andes enter a period of extreme weather. Specifically, an Ojos del Salado winter brings winds exceeding 100 km/h and temperatures dropping below -30°C at the summit. The mountain transforms completely.
During these harsh months, the famous crater lake freezes over. Furthermore, heavy snowfall buries the route markers from the previous summer. The winter weather does not simply pause the mountain; it rebuilds it with relentless force, creating new ice formations and challenging terrain that we will face in the upcoming season.
The Climbing Window
The ideal window to climb Ojos del Salado (November to March) is notoriously narrow. It exists thanks to periods of atmospheric calm that temporarily halt the strong winter storms. Therefore, successfully reaching the summit requires great precision and timing.
Professional operators understand that success depends on reading the local weather accurately. We constantly evaluate the wind, clouds, and terrain conditions. The harsh winter weather that appears to shut down the peak is, in reality, preparing it for that brief and valuable summer window.
Summer Ascents Are Planned in Winter
At HME, these cold months represent a time of intense planning. We actively update routes, renew equipment, and prepare the Laguna Verde base camp to ensure an impeccable operational standard.
For you, the real work happens at home. Preparing your body for 6,893m demands months of structured physical training. The mountaineers who conquer the summit in January started their rigorous preparation in the middle of winter. Those who arrive without preparation simply do not reach the top. It is an unbreakable rule.
