As a general rule, the temperature decreases by about 1 degree Centigrade per 100 meters of altitude. If the temperature in the lowlands is 20 degrees, it can be about 0 degrees at 2000 meters above sea level. For excursions in the mountains (above 2000 meters), it's important to have good equipment and warm clothing because it can snow at times. The weather can also change quickly in the course of a day. Obtain information before mountain tours and excursions so that you have the right equipment and clothing with you.
