It is important to keep this in mind when planning your trip to Peru’s coast, especially if you plan to take part in activities such as surfing or sailing.
It is the warming of sea waters off the coast of Peru and the climatic changes it generates at the regional and global level, bringing drizzle, especially in Tumbes, Piura, Lambayeque, La Libertad, and Lima.
