Stargazing at Black Forest National Park: when is the sky clear and dark?
March is the best month for stargazing at Black Forest National Park: on average 40 clear, moonless hours of full darkness, and 24% of nights have at least two of them (ERA5, 2006–2025). The darkest spot we found there is darker than 49% of Europe’s land (NASA VIIRS 2025).
