Portugal’s breathtaking coastline is renowned for its beauty and adventure. But this January, travelers are urged to take extra precautions as IPMA (the Portuguese Institute for the Sea and the Atmosphere) has issued a yellow weather warning for rough seas along the mainland Atlantic coast. Visitors planning coastal trips should stay alert as massive swells of 4 to 5 meters are forecast, creating challenges for beachgoers and water activities alike.
The alert, which will be in effect from January 20th to January 21st, 2026, affects multiple coastal districts across Portugal. With rough seas in the forecast, activities such as boating, fishing, and water sports could face significant disruptions, and travelers should adjust their itineraries to ensure safety.
Yellow Warning: Portugal’s Coastal Adventure is Set for a Wild Ride
IPMA’s yellow warning indicates that travelers and locals should expect potential disruptions due to hazardous conditions along the coastline. The weather alert is linked to north-west waves that could reach heights of up to 5 meters, creating dangerous marine conditions. Whether you’re an adventurer seeking thrilling waves or simply strolling along Portugal’s picturesque shores, it’s crucial to heed these warnings to avoid unnecessary risk.
For the next two days, coastal and maritime activities could be highly affected, including ferries, small vessels, and recreational boating. While the yellow warning is the lowest tier in IPMA’s system, it still signifies potential risks for those unprepared for the surf. With conditions likely to worsen, travelers are advised to monitor real-time updates directly from official weather channels.
Why the Rough Seas Could Impact Your Portugal Adventure
The warning covers some of Portugal’s most popular coastal areas. From the beautiful beaches of Algarve to the historic coastal towns of Lisbon, visitors are advised to adjust their plans. The strong surf could influence tourism activities, particularly in coastal towns and harbours. For those enjoying seaside strolls or planning fishing trips, the sea’s unpredictable temperament could make it dangerous.
In addition to the powerful waves, IPMA is predicting strong winds that may further complicate conditions. The warning is in effect from midday on January 20th through 09:00 on January 21st, 2026. IPMA will continue to provide updates, but the message is clear: caution is key for travelers hoping to explore the coast during this period.

Water sports companies, ferry services, and beachside hotels may experience interruptions or delays.

For tourists planning to visit Portugal during the warning period, it’s important to:
Check with local authorities for weather updates.Review any maritime travel schedules for potential changes or cancellations.Reconsider non-essential coastal activities, such as surfing, fishing, or boat tours, until the conditions improve.
Even though the sea looks inviting, these rough conditions demand extra vigilance and respect for nature.
