The answer is Portugal. The Eastern Europen countries that lie in the Balkan peninsula are Balkan states. Portugal is located in the West of Europe. Balkan countries are located in the southeastern of Europe; composed of 12 countries. These states are close to the Black Sea. The Northern boundary of the peninsula varies (hence also the number of states considered Balkan) especially influenced by historical and political connotations. This is why Turkey is also considered Balkan country.
In general, the highest relative humidity is observed NEAR SUNRISE and the lowest relative humidity is observed during MID-AFTERNOON.
Relative humidity is inversely proportional to temperature. The colder the climate, the higher the relative humidity. The hotter the temperatures outside, the lower the relative humidity.
Relative humidity increases as the air temperature falls at night and peaks at dawn.
Temperature peaks during mid-afternoon, thus relative humidity is at its lowest.
