Start with energy
Wave height and period indicate how much offshore energy is approaching, but not the exact breaking wave at a beach.
LIVE PORTUGAL SURF
Read the coast before you go.
Watch wave energy, swell direction and coastal wind change around mainland Portugal, Madeira and the Azores, then check whether Nazaré could produce a worthwhile big-wave viewing window.

HOW TO READ IT
A better first glance—not a green light to enter.
Follow direction
Headlands, islands and beach orientation decide whether a swell reaches a particular break or passes it by.
Finish at the beach
Check tide, wind, currents, access, lifeguard status and local warnings before deciding whether to enter.

When could Nazaré turn big?
A seven-day travel-planning signal built from hourly offshore wave height, swell period, direction and coastal wind.
Reading the latest Atlantic model…
Checking the next seven days around Praia do Norte.
The forecast starts the conversation. It does not finish it.
Portugal’s coastline changes quickly between beaches. Treat every unfamiliar break as a new place, even when the offshore numbers look familiar.
Check the actual beach
Look at the tide, wind, currents, access, lifeguard status and any local warning before entering. Offshore wave height is not breaking-wave height.
Ask someone local
A nearby surf school or experienced local surfer can explain hazards that a model cannot show, including rocks, rips, channels and safe exit points.
Know when to watch
At Nazaré and other exposed coasts, the safest plan may be to stay on an established viewpoint. Respect barriers, closures and maritime authority instructions.
