Ocean Shores features a marine climate controlled by the Pacific Ocean which means summers aren't too hot and winters aren't too cold. It's always a bit windy which means you can fly a kite every day of the year.
If you are planning a visit you should plan on layering just about anytime of the year. It will probably be windy so even if the temperature is fairly warm you can still get a wind chill. If it's raining don't bother with the umbrella, it will just get turned inside out in a gust of wind, opt for hats and hooded coats.

You may have seen footage from Ocean Shores on local news stations during winter storms in the past. This is actually a fairly popular destination for people who enjoy storm watching. Due to it's location on a coastal peninsula, Ocean Shores tends to get pretty extreme winds and therefore the waves/tides can get extremely rough on the beach during winter storms. Even during the calmer days it is almost always windy enough on the beach to fly a kite.
When it's very hot in Western Washington moisture draws from the ocean and the entire coast can be completely foggy despite the warm and sunshine only a few minute drive inland. This is one of the main attractions for people who swarm to Ocean Shores to escape the extreme highs only a couple hours drive inland.
