Question 1

When is the best time to dive in Portugal?

Accepted Answer

For most divers, the best overall window is late spring through early autumn, when seas are calmer and water is warmer. Summer typically brings the most consistent island season in the Azores and comfortable conditions in the Algarve, often around {{ 20 | temperature }} to {{ 24 | temperature }}. The mainland west coast can still be windy and surge-prone, so plan early dives and stay flexible. Winter can work in sheltered areas, but expect colder water near {{ 14 | temperature }} to {{ 18 | temperature }} and more swell-driven cancellations.

Question 2

Where should I base myself for Azores diving in Portugal?

Accepted Answer

For first-time Azores visitors, the easiest base is [Ponta Delgada (Sao Miguel Island - Azores)](https://divejourney.io/destinations/ponta-delgada-sao-miguel-portugal) because it has the main airport, lots of dive operators, and a mix of shore and boat access. Build a week around coastal sites like [Ilheu West](https://divejourney.io/dive-spots/portugal-ilheu-west), then add offshore goals when forecasts align. The Azores are weather-driven, so schedule extra days to catch calm windows, especially if you want blue-water sites.

Question 3

How cold is the water for diving in mainland Portugal?

Accepted Answer

Mainland Portugal is temperate Atlantic. Around Lisbon and the central west coast, nearshore temperatures commonly range from about {{ 14 | temperature }} in late winter to roughly {{ 21 | temperature }} in late summer, with upwelling sometimes making summer days feel cooler than expected. The Algarve south coast is typically warmer and can feel noticeably more comfortable in summer and early autumn. If you are sensitive to cold, plan for thermoclines and prioritize the Algarve, Madeira, or summer island trips.

Question 4

What wetsuit do I need for diving and snorkeling in Portugal?

Accepted Answer

Suit choice depends on region, month, and your cold tolerance. Mainland west-coast dives can feel cold outside summer, especially if water sits near {{ 14 | temperature }} to {{ 18 | temperature }}, so many divers prefer a warmer setup and consider a hood for comfort. In the Algarve during peak summer, water can reach about {{ 22 | temperature }} to {{ 23 | temperature }}, which often suits lighter exposure. For the Azores and Madeira, expect a mid-range setup that stays comfortable from about {{ 18 | temperature }} to {{ 24 | temperature }} depending on season.

Question 5

How do I visit Berlengas for snorkeling or diving?

Accepted Answer

Berlengas is typically visited by day boat from Peniche, and access is managed, so plan to book ahead (especially in summer). Treat it as forecast-dependent: calm seas are the difference between an easy day and a cancellation. Snorkelers often enjoy coves near [Forte de Sao Joao Baptista](https://divejourney.io/dive-spots/portugal-forte-de-sao-joao-baptista), while scuba divers target deeper structures like [Vapor do Trigo (Wreck)](https://divejourney.io/dive-spots/portugal-vapor-do-trigo-wreck). Bring warm layers for wind, and follow reserve rules for waste and landing areas.

Question 6

Is Portugal good for beginner scuba divers?

Accepted Answer

Yes, but pick regions carefully. Beginners often do best in the Algarve and in sheltered mainland bays where surge is lower and entries are simpler. Choose calm days with visibility near {{ 10 | visibility:m }} or better, and avoid exposed west-coast sites when swell is running. The Azores and offshore days can be more advanced due to current and blue-water ascents, so build experience first or book specifically beginner-friendly itineraries. A local operator is the fastest way to match sites to your comfort level.

Question 7

How do I plan around the Nortada winds on the west coast of Portugal?

Accepted Answer

In summer, persistent northerly winds can build afternoon chop and reduce comfort on the west coast, often around {{ 20 | wind:kph }} to {{ 40 | wind:kph }}. The simplest strategy is to dive early, then schedule topside activities for the afternoon. Keep a plan B on the south coast or in sheltered bays. If you are traveling for a short window, consider basing in the Algarve for more consistent conditions, or build a flexible itinerary that lets you switch coastlines when forecasts shift.

Question 8

Are there sharks in Portugal and where are the best chances to see them?

Accepted Answer

Portugal's best chances for shark encounters are typically around island offshore environments, especially the Azores, where blue-water days can bring pelagic wildlife. On the mainland, encounters are less common in typical recreational dive zones. As always, shark experiences should be respectful: keep distance, avoid chasing, and follow operator procedures. If sharks are a priority, base in the Azores and build slack days into your schedule so you can wait for calm, clear conditions.

Question 9

Do I need permits or special rules to dive in marine reserves in Portugal?

Accepted Answer

Rules vary by protected area, but you should expect zoning, activity limits, and strict no-collect behavior. Berlengas access is managed for visitors, and Madeira's Garajau reserve has specific regulations for recreational diving that local dive centers typically handle. In the Azores, a large network of marine protected areas includes offshore zones, and wildlife interaction is regulated. The easiest approach is to dive with a local operator in protected areas and follow briefings about where you can go and what is permitted.

Question 10

How do I handle a diving emergency or decompression sickness in Portugal?

Accepted Answer

If you suspect DCS or any serious diving injury, stop diving and call 112 immediately. Tell responders it is a diving accident and follow medical instructions. Keep the diver warm, hydrated if appropriate, and on oxygen if available and trained to administer it. Portugal has access to hyperbaric medicine capacity, and emergency services coordinate transport and treatment pathways. If you have DAN coverage, follow their emergency procedures and keep your membership and policy details accessible offline so you can provide them quickly during coordination.
