The Pacific state of Oregon is bordered on the south by California and Washington to the north. The state capital is Salem, but the most populated city is Portland. Oregon has a diverse topography from the Cascade Mountains with their many glaciated volcanoes to it’s windswept Pacific coastline. Mount Hood is the highest point within the State at 11,250 feet (3,429 meters).

The temperature varies considerably throughout Oregon, but temperatures in the coastal region during the winter months can dip to 27f/-3c and in the summer months average 72f/22c. Probably, the best description of the climate would be to say that Oregon has cool, but not cold winters and warm, but not hot summers.

Scuba diving in Oregon is an interesting choice from Pacific coast to volcanic crater at high altitude! So make sure you understand how to set your dive computer for altitude diving, but what an experience.

There are two craters that offer great opportunities. Firstly and not surprisingly by name, Crater Lake and then followed by Waldo Lake. Crater Lake has an approximate depth of nearly 600 meters/1950 feet and an approximate height of 1885 meters/6180 feet above sea level. The most distinctive features about Crater Lake are the colours and visibility (100+ feet). In it’s own right, it is a tourist attraction just because of the amazing indigo blue water. Definitely one to have in your dive log. Waldo Lake is a similar lake with good clarity, but not quite matching that of Crater Lake.

Coastal diving is a challenge as the weather can be rather temperamental. Visibility ranges from 6 to 30 feet and the water temperature during the summer period, from May through to September ranges from 10c (50f) to 18c (65f).
