Costa Rica’s Caribbean and North Pacific coasts are bracing for significantly rougher sea conditions this weekend. “We are going to experience an increase in trade winds, which will also drive higher surf, mainly in the Caribbean and North Pacific,” Mora stated. Caribbean Coast: Escalating Through SundayAverage wave heights in the Caribbean hovered around 1.5 meters during the week. However, building trade winds will push waves past the 2-meter mark on Saturday and Sunday. North Pacific & Gulf of Papagayo: Rough Seas OffshoreThe largest waves of the weekend will concentrate offshore in the North Pacific, particularly surrounding the Gulf of Papagayo.
