Giant waves are expected to return to Nazaré, Portugal, between Wednesday, November 18 and Friday, November 20, 2026. A powerful Atlantic swell is forecast to reach Praia do Norte, potentially producing waves exceeding 15 metres (49 feet). According to specialist forecasting website Nazaré Waves, Thursday, November 19 could bring the most spectacular conditions, while Friday morning may offer the best opportunity for big-wave surfers.
After several days of relatively small to medium-sized waves and unfavourable winds, conditions are expected to change significantly from November 18. The approaching swell could produce another impressive display along this stretch of Portugal’s Atlantic coast, which has become internationally renowned for its extraordinary waves.
November 18–20: three days to watch in Nazaré
According to forecasts published by Nazaré Waves, the swell should build rapidly throughout Wednesday, November 18. Waves could exceed 8 metres (26 feet), marking the beginning of a new period of powerful surf at Praia do Norte.
Thursday, November 19 could be the most spectacular day. If the swell develops as expected and wind conditions allow, some waves could reach heights of more than 15 metres (49 feet). Such conditions would offer an impressive spectacle for visitors watching from the cliffs above the beach.
However, Friday morning, November 20, may provide the best conditions for big-wave surfing. Forecasts suggest lighter winds and cleaner, better-shaped waves, potentially creating a more favourable window for experienced surfers and their support teams. The swell is expected to gradually lose strength as the day progresses.
Wind will remain the main factor to watch, particularly on November 18 and 19. Strong gusts could disrupt the shape of the waves and make surfing difficult, even if the swell reaches exceptional heights.
Where to watch Nazaré’s giant waves
For visitors hoping to witness the event, the headland surrounding the Fort of São Miguel Arcanjo remains Nazaré’s most famous viewing location. Overlooking Praia do Norte, the historic fort offers an elevated perspective on the Atlantic and the area where the largest waves break.
The viewpoint has become closely associated with Nazaré’s big-wave surfing scene, attracting photographers, spectators and surf enthusiasts whenever a powerful swell approaches. Watching from the cliffs can be particularly impressive when the waves are large enough to produce towering walls of water and enormous bursts of sea spray.
However, the arrival of giant waves does not automatically guarantee a surfing session. Experienced big-wave surfers and their teams assess the swell, wind and rescue conditions before deciding whether it is safe to enter the water.
Visitors should also respect any access restrictions around the fort, cliffs and exposed coastal areas. Large waves can create dangerous surges and powerful spray, including in places that may initially appear to be a safe distance from the shoreline.
November 18, 19 and 20 are therefore the key dates to keep in mind for the next major swell expected at Nazaré. Forecasts will continue to develop as the event approaches, helping to identify the most promising hours for watching the waves and, potentially, witnessing another memorable session of big-wave surfing.
