São Martinho do Porto / Foz do Arelho (Lagoa de Óbidos)
Weather only, by design
Lagoa de Óbidos is a sheltered coastal lagoon. Open-Meteo's marine model has no coverage inside it — it would answer a lagoon query with the nearest ocean cell — so this page shows no calmness score, wave height, sea state or water-temperature forecast. Wind, air temperature and UV are genuinely forecast for the lagoon area.

Know before you get in
- Strong currents near the inlet and the sandbanks.
- No jumping or diving from the old Foz do Arelho pier — submerged objects.
- In the bathing season, no boats, boards or kites in the lower lagoon.
- Lifeguards only in the official bathing season (mid-June to mid-September).
- The lagoon is tidal — the water rises and falls, less than at the coast.
- The bottom drops steeply in places at Foz do Arelho.
