Summers in the Netherlands can be a genuine celebration with the sun, sea, beach, festivals, music, overnight stays, lovely pavement cafés, delectable food, and fine wine! The longest day of the year, or the Summer Solstice, which occurs on June 21, marks the beginning of summer, according to the astronomical calendar. June, July, and August are regarded as the summer months by meteorologists. As a result of its maritime climate, which is influenced by the North Sea and the Atlantic Ocean, the Netherlands experiences a variety of weather conditions throughout the summer, including a few hot days with temperatures considerably over the 25-degree threshold.
