What's the climate like in Amsterdam?

The climate is pleasant, and the weather conditions are mainly affected by the airflow from the North Sea. The temperature in winter is mild, rarely below 0℃. According to the latest rating of the US Department of Agriculture, Amsterdam and most parts of North Holland, which are located at the northern end of the European continent, belong to Grade 9 cold-resistant areas. Frost may occur in some areas due to the cold current from continental Europe, Scandinavia, Russia and Siberia. Because Amsterdam is surrounded by water on three sides, the heat island effect is strong, and the temperature is rarely lower than -5℃ at night, but the lowest temperature can reach-12℃ in the southeast suburb of Hilversum, 25 kilometers away. Summer is warm but not hot. The average maximum temperature in August is only 22℃, and the high temperature above 30℃ is generally only about 3 days. The average annual precipitation in this city is about 175 days, but the average annual precipitation is less than 760 mm. The rainy season generally lasts from 10 to March of the following year, and the precipitation mode is mainly light rain. The city is occasionally hit by storms.
