Most beach logos have a similar look and feel. They often use bright and contrasting colors and incorporate beach-related elements like waves, the sun and beach sand. The colors used in beach-related logos also resemble these elements with a lot of blue and shades of yellow being used.
The sun is a great logo element as it is very easily recognizable and it conveys a feeling of warmth and happiness.
Another obvious element that relates to the beach and it used quite often are the symbols that resemble water or waves. Some use it as the center of the logo while others subtly incorporate it in a way that isn't immediately visible.
