About Leiden weather

Leiden is in Gemeente Leiden, Netherlands at 52.16°, 4.49°. Right now it’s 11° and partly cloudy; today’s high is 14° with a 50% chance of rain.

The Netherlands' flat, low-lying terrain and North Sea exposure create a maritime climate characterized by mild temperatures, persistent wind, and frequent rainfall spread throughout the year. With much of the country at or below sea level, weather and water management are deeply intertwined in Dutch life. Cloud cover is prevalent, with the country averaging only about 1,600 hours of sunshine per year — significantly less than southern Europe.
