Portugal Shark Attacks: Risk Forecast & Recent Reports

What beaches in Portugal have the highest shark risk?

No specific beaches in Portugal are consistently identified as having "high shark risk" due to frequent incidents; reports are extremely rare across the entire coastline.

Historically, commercial fishing records indicate blue sharks (Prionace glauca) and shortfin mako sharks (Isurus oxyrinchus) are present in the deeper offshore waters of Portugal, particularly around the Algarve and Alentejo coasts. These pelagic species are not typically found close to shore in areas frequented by surfers or swimmers, minimizing direct interaction. The deep waters off Nazaré, famous for its big waves, also have a diverse marine ecosystem, but no recorded increase in shark encounters for surface users.

What shark species are most common around Portugal?

The most common shark species found in Portuguese waters, particularly offshore, include the blue shark and the shortfin mako shark.

Other species occasionally encountered further from the coast include the thresher shark (Alopias vulpinus) and various smaller catsharks. Great white sharks (Carcharodon carcharias) have been sighted in the wider Atlantic, but confirmed sightings close to Portugal's coast are extremely uncommon. The vast majority of these species pose little threat to surfers or swimmers due to their offshore habitats and typical prey.

When is shark activity highest in Portugal?

Shark activity in Portugal, particularly for pelagic species, generally peaks during the warmer months from late spring through early autumn, typically June to October.

• June-August Activity

  These months bring the warmest Water temperatures, potentially increasing pelagic shark movement offshore. Our shark risk forecast accounts for these seasonal changes.

• September-October Activity

  Water temperatures remain warm, and baitfish might be more active, drawing species further. For surface users, however, this seasonality primarily affects offshore environments.

• November-May Activity

  Cooler waters prevail, and overall shark activity is generally lower, especially closer to shore. Nearshore shark presence remains very low year-round.

How should you stay safe surfing in Portugal?

To stay safe while surfing, spearfishing, or swimming in Portugal, always check current ocean conditions and be aware of your surroundings, even with the very low shark risk.

Consider the following safety practices:

Check Forecasts

Always review the global surf forecast and any local reports before heading out. Our platform provides comprehensive data, including Water temperature (which is typically 60-70°F in summer along the southern coast), swell conditions, and visibility. For the most current information, you can download SafeWaters.

Avoid Low Visibility

Do not enter the water during periods of low visibility, such as after heavy rainfall, near river mouths, or at dawn/dusk. Poor visibility can hinder your ability to spot anything unusual and can affect a shark's ability to distinguish prey.

Stay in Groups

Always enter the water with at least one other person. Groups are generally safer, and you can look out for each other. Avoid isolated areas.

Avoid Attracting Sharks

If you are spearfishing, promptly remove any caught fish from the water to avoid attracting sharks. Do not wear shiny jewelry, which can mimic fish scales.

What recent shark encounters have happened in Portugal?

There have been no documented unprovoked shark encounters with surfers, swimmers, or spearfishermen in Portugal in recent years that align with what is often reported as a "shark attack" in global news.

The extremely low number of incidents highlights Portugal's coastline as generally very safe for water activities. While marine life, including sharks, exists in the ocean, direct harmful interactions with humans are statistically rare. You can review the latest shark encounter news globally, but it is important to contextualize any reports with local data for Portugal, where incidents remain exceptionally uncommon.
