No, they were the opposite. Pacific ocean brings you large waves which is great for surf but is dark and merky water. Also volcanic sand is pitch black so it doesn't help making the ocean any brighter. There are areas with not so dark sand of course but it's not the case for the surf city beaches.
Yeah, it's the same in Acapulco and Rosarito too on that side of the country. But I heard that some places in Oaxaca do have the lovely blue waters. You wouldn't catch me swimming in those murky waters...I like to see what's there...
