You'll find comfortable temperatures great for exploring the nearby Lagoa de Óbidos or enjoying the coastal walks. The local restaurants and attractions are fully operational, but you'll experience a more relaxed pace.For those prioritising warm beach holidays and sunshine, the summer months of July and August are also excellent. This is peak season, so while it can be busier, the weather is consistently hot and sunny, great for enjoying the beaches of Foz do Arelho or water sports on the lagoon. It's a great time for families, with plenty of activities and a lively option.If your focus is on surfing or other water sports, the autumn and winter months can offer more consistent swells, though the weather will be cooler.
