In the period 1960-2015, the mean sea level along the Slovenian coast increased by 10 cm. On average, this means by 1.7 mm/year and in the last 20 years by 5 mm/year. It is estimated that the increase of the middle sea level is affected by global see level increase, and in the last period also by extreme weather conditions in the region. In the last twenty years, at the Slovenian and in the Adriatic coast sea level has been rising faster than the European and global trends. In case the current trend continues, and if infrastructure adaptation will miss its goal, the daily flooding of low-lying urban areas of the Slovenian coast is expected by the end of the century. It is estimated that the Europe's sea level is going to rise by 20 to 80 cm. The frequency of floods will therefore be increased by a factor of 10 -100.

Phytoplankton biomass express as chlorophyll a concentration reflects changes in nutrient content in marine environment. Slovenian sea is evaluated in good or very good status regarding phytoplankton biomass and values of phytoplankton biomass are showing a positive trend.
Quality of bathing water in coastal zones in Slovenia is very good. It deteriorated only in turbulante weather.
