Rain reaches its maximum intensity in autumn. The rainiest areas are the west coast as well as the northern and central regions of the country, where the mountains lie. The more altitude, the lower the air temperature and humidity. The weather tends to change almost every few kilometres.
In general, the beginning of September is quite friendly to tourists. The average daily temperature is about +18 ° C; sunny days are also possible. However, in October and November, it is already cool, and the weather changes to squally winds. In the last month of autumn, it usually snows in the hilly areas. Some mountain rivers at higher altitudes overflow their banks, flooding entire villages.
