During the summer months (June-September), the water warms up to a more comfortable 18-21°C (64-70°F). Spring and autumn offer transitional temperatures.

When is the best time to visit Sesimbra, Portugal?

During these months, you'll find the warmest water temperatures, calmer sea conditions, and generally better underwater visibility.

The summer offers the most reliable and comfortable diving experience.
What's the visibility like during the dive season in Sesimbra, Portugal?
Underwater visibility in Sesimbra, Portugal, can be variable. During the prime dive season from summer to early autumn, visibility typically ranges from 10 to 20 meters (33 to 66 feet). However, it can occasionally exceed 25 meters on exceptionally clear days. Plankton blooms, especially in spring, or recent storms can reduce visibility significantly, sometimes down to 5 meters or less.
Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Sesimbra, Portugal?
Sesimbra, Portugal, is not known for large-scale migrations of manta rays or whale sharks. However, you might occasionally spot sunfish (Mola mola), especially during the summer and autumn months, as they come closer to the surface. Dolphins are also frequently seen from the dive boats year-round. The primary attraction is the rich resident biodiversity within the marine park rather than specific migratory events.
