Take A Drive
The Oregon Coast is full of great destinations including the famous Tillamook Cheese Factory in Tillamook, Oregon, the Newport Beach Aquarium in Newport Beach, Irelands Rustic Lodge, located in Gold Beach Oregon and many many more. The Oregon Coast is known for its predictably unpredictable weather. You can be assured though that if your stay is longer than three days you will be able to see the sun shinning through and have a gorgeous day on the beach. That of course is not to say that it won't be a good day if its cloudy, it just wont be as warm.
The oregon Coast has an abundance of lighthouses that are open for tours and are great stops down Hwy 101. Some are located on the edge of bays so the winds can be in the upper 80 MPH range but it sure doesn't take away from the beauty.
As I mentioned before the Oregon Coast doesn't have the warmest beach goers weather but the farther south you head the warmer it will get. Once you get down to Brookings, Oregon then you are looking at some pretty decent beach temps.
