Sea levels in Portugal

Many buyers of real estate in Portugal also consider the proximity to the coast when choosing the right region. An increasing factor is the rising sea level due to climate change. Unfortunately, we have to deal with this, even if the effects will only show in a few decades. Worldwide, sea levels can rise up to 82 cm by the end of the century. By 2050, the world climate experts forecast an increase of 17 to 38 centimeters.


The 2013 World Climate Change Report also points out that rising water levels could be associated with ocean storms. One can assume that the effects of rising sea levels in Portugal will not be as severe as for other nations in Europe. Portugal has already started to remove many buildings that were built too close to the water in coastal regions. This action caused a lot of displeasure among the owners, but from a geopolitical and environmental perspective, it makes sense.

Which regions will be affected most by rising sea levels?

The scientific organization Climate Central provided simulations for the coming decades of the global increase in the seas. Of course, these simulations are not entirely accurate and there are many other effects on the actual sea level. Nevertheless, we would like to provide the results of a simulation for Portugal in 2040, as they can be a useful guide for buying a house.


The most affected regions in Portugal according to Climate Central are the coasts of:

  • Aveiro
  • Figueira da Foz
  • Samora Correira region
  • Comporta
  • Lagos (Algarve)
  • Alvor
  • Portimão
  • Vilamoura
  • Faro
  • Olhão
