Instituto Português do Mar e da Atmosfera

A state institute that publishes data and warnings on the sea, the weather, seismic activity and other natural phenomena. In everyday life you come across it when checking sea conditions, the waves, the water temperature or official warnings. For people living on the coast and anyone heading to the beach, it is a particularly useful source.

Where you come across it. Forecast websites, the news, and warnings about the sea and natural conditions.
