Ytre Oslofjord

The Ytre Oslofjord extends 65 kilometers south from the Hurumlandet peninsula to the Færder Lighthouse, forming the outer section of the Oslofjord system.

The waterway carried the name Christianiafjorden from 1624 to 1925, reflecting the former name of Oslo, and previously was known as Fold.

The fjord waters influence the daily activities of 1.6 million residents living in municipalities along its shores, representing a significant portion of Norway's population.

The inlet maintains the highest year-round temperatures in Norway, with an average of 7.5 degrees Celsius, peaking in July at 17.2 degrees Celsius.

The passage narrows at Drøbak Sound, creating a natural division between the outer fjord and the inner Oslofjord near the Hurumlandet peninsula.
