The climate of the Danube Delta is continental with strong influences from the vicinity of the Black Sea and its prevalent amphibian environment. It is the driest and sunniest region (70 days with blue sky, 2500 hours of sunshine/year) of Romania. The mean annual temperature is 11°C (-1°C in January and 22°C in July), with min precipitation between 400 and 300 mm/year, decreasing from west to east. The evaporation is around 1000 mm/year, favorized and amplified by the strong and frequent winds, resulting in long periods of drought in the summer. The northwest winds cause frequent storms in spring and autumn. In the interior of the Delta, the continental character of the climate is very pronounced.
