The tallest structure in Westport that has any sort of habitable piece to it is the Coast Guard tower that acts sort of like a lighthouse to the surrounding boat traffic, and helps those on the beach as well by giving a good idea of Ocean conditions.
The tower displays a flag during the day, and a colored light in the glassed-in part of the structure at night. The light isn't bright enough to be considered a light house, but it is enough of a light to be visible for some distance away. Thus, it helps provide a warning for those in the area.
On February 15, 1989 the National Weather Service officially discontinued its program of Coastal Warning Displays. However, on June 1 of 2007, the US Coast Guard re-established a display system at selected small boat sites. The National Weather Service prefers that people listen to the detailed information available on the NOAA radio network as that provides quite a bit better information to weather conditions. However, at certain sites it was decided by the US Coast Guard that a visual display would be extremely helpful.
The web site given below describes the meaning of the flags and lights (about halfway down the page). As the ocean is always fairly rough in this area, there is almost always a red flag or light (meaning small craft advisory). Anything more than that means there is some rough stuff coming.
There are quite a number of potential hazards with the waves and large rocks that make up the breakwater and the sea wall at Westport.
Now, there is no specific rules stating that you have to be sane and that you need to keep from killing yourself on the rocks. As seen on the sign in the first photo: you are welcome to go out on the rocks and get washed off of them, and kill yourself.
Indeed, the guy in the wet suit and surf board appears to be doing just that in photo 2. Just what, exactly he was attempting to do with a surf board on a bunch of large rocks being pounded by huge waves is a matter of speculation. However, whatever it is most likely will lead to significant injury of some sort.
As seen in photo 3, it is quite possible, even likely, that waves will wash over the surface of the rocks. Keep in mind, these photos were taken on a day that really didn't see huge waves. If a storm were happening off the coast somewhere, you can bet that the waves would be even larger.
Also, keep in mind that you can not run on these rock surfaces because they are very rough. They are intended as breakwaters not as walking pathways. If large waves start to hit and you are far out on the breakwater, you are going to have a lot of trouble getting back to shore and really fight not getting washed out to sea.
Getting washed off the rocks pretty much means certain death, as the heavy waves will grind you to a pulp against the rocks of the breakwater or the sea wall. Large waves will contain a lot of very heavy logs and other debris which will tend to grind you into a pulp if you don't get washed off the rocks. Just look at photo 1 again. All that lumber on the sea wall didn't just appear there by falling out of the sky - it was washed up on top of the sea wall by very heavy wave action.
Certainly, people have gone out there and lived, but at the same time I would not recommend doing it, and if you do it you will want to be very aware of all the hazards surrounding you, and head back if something changes.
There are quite a number of camp sites in the area of Westport, and even a few recreational vehicle facilities right in the downtown area.
However, it is vitally important that no food be left out anywhere at all. Even in locked containers your food is subject to search and seizure by the local raccoon population.
The large rocks that have been dumped along the shore for nearly 120 years have many large gaps and crevices in them. This makes them great hiding places for raccoons, and you can bet that if any tidbits of any sort are discovered, any attempt to take them will be made.
The raccoons certainly are not especially shy either, though they have enough sense to hide in the rocks most of the time. Usually, you will only see a head or a few eyes sticking out of the rocks, but if people are far enough away they will come out of the holes completely.
So, it is necessary to not only have a lockable food container, but it is best to keep the food in your vehicle if possible. If you do need to leave it outside, it must be a heavy enough container that it can not be stolen or otherwise picked up and moved by small hands. Remember these are very clever and determined creatures when it comes to stealing food from any source, and they will eventually figure out how to open most containers - even if they are nearly impossible for people to open. Unlike bears, cougars or most other wildlife found in the Pacific Northwest, they have very small and nimble hands that are very adapted to opening all manner of containers.
Even then, don't be surprised if your food container is at least moved or knocked off the picnic table or otherwise tampered with. It isn't that there are dozens of starving people in Westport, just quite a number of some very opportunistic (and fairly well fed) unsavory characters of the masked four foot variety.
Do yourself a favor, do not risk ruining your trip by getting seasick, get yourself some dramamine. Even the deckhands get sick on the Pacific. I did not take this picture from a fly bridge! This was shot while in the bottom of a 15 foot swell.
