Warm spring sun produced corn snow in the central Andes. Farellones hit 6°C; Valle Nevado, El Colorado, Portillo and Las Leñas all report corn snow.
Farellones topped the list on Sunday, reaching 6°C in the Región Metropolitana de Santiago and producing textbook spring corn snow. The warmth softened surfaces early, so runs that saw morning freeze were already turning over by late morning. That temperature separates Farellones from its neighbours today, offering the kind of punchy, friendly corn that makes low-angle cruising and high laps equally satisfying.
The rest of the central Andes settled into a narrower band of conditions. Valle Nevado held at 0°C with corn snow across open faces and platter-served bowls, while El Colorado sat at 1°C and Portillo at 2°C, each reporting the same spring surface. Those Chilean resorts share a similar rhythm, firm first thing then sweetening through the day. Across the border, Las Leñas in Mendoza matched Valle Nevado at 0°C and offered corn on most tracked and untracked slopes. None of these places saw fresh accumulation; instead the day is defined by preservation and transformation of what is already on the hill.
Taken together, the readings point to classic spring skiing for the next day or two. Nights near or below freezing will lock in a firm morning crust on exposed steeps, while daytime sunshine and single digit temperatures at lower altitudes will convert that crust into punchy corn by mid to late morning. Terrain choice will matter; higher, wind-protected lines will hold a cleaner, more consistent corn, while lower treeline runs will soften fastest. There is no sign in the data of new snowfall to reset surfaces, so expect evolution rather than renewal in conditions.
