Above 3000 metres is where cold, subpolar climates dominate and where frost and occasional snow become more commonplace. The subpolar oceanic climate (Köppen "Cfc"), existing between 3,000 and 3,500 metres, can be found on the mountain slopes of Indonesia's highest peaks, and serves as a transition between oceanic climates and tundra climates. Tundra climates (Köppen "ET"), are found anywhere above 3500 metres on the highest peaks of Indonesia, including the permanently snow-capped peaks in Papua. In this climate regime, average monthly temperatures are all below 10 °C, and monthly precipitation is uniform.
