Even in high summer the temperature is usually below freezing point and often around -5C to -10C. On a calm sunny day this temperature can feel pleasant and a short break can even be taken on the summit to admire the views and enjoy a sandwich. However with cloud and wind chill this can feel seriously cold and any skin exposed to the wind will need to be covered to avoid frost nip. Ascents outside the main summer season take on a much more serious feel as the mountains climate is more akin to Arctic or Himalayan conditions than classic summer alpine. Temperatures as low as -40C have been recorded in winter.
