On Helgoland Nordstrand, most of the year, there are quite a few people.
From November to April the water at Helgoland Nordstrand is too cold to swim in.
From July to January Helgoland Nordstrand has rainy season. This is something to keep in mind when planning your trip since it is quite possible that you may be unable to sunbathe.
