Weather-wise: be prepared for rain. The Oregon coast, like Washington State, can be really nice, and it could really rain. [I lived in the Tacoma, Washington State, area, from 1973 to 1977, courtesy of the US Air Force...and drove the Oregon coast one or two times.]
Depending on what the weather is off the Pacific, low pressure = rain; high pressure = no rain.
Just be prepared for rain....
