The tourism sector will be particularly affected by climate change, but there have been few studies specifying the impacts of climate change on tourism for a certain country. This paper considers the impacts of climate change on tourism in Spain.

A description is made of the Spanish Harbours tide gauge network (REDMAR), especially focused on the status of the Mediterranean stations.

Sea level is monitored in Spain by various agencies for different applications: control of the national levelling system, oceanographic studies, climate change, operational purpose, harbour operations, navigation, etc.

Resumen: El cambio climático es innegable y España es uno de los países más vulnerables de la Unión Europea (UE).
