How to read the scale
The current engine supplies LOW, MODERATE and HIGH through its existing offshore signal. NONE, VERY HIGH and EPIC are reserved until a validated source distinguishes them. Missing or expired data never activates a level.

OFFSHORE ARCHIVE
Highest offshore HMAX readings
Top 5 qualifying hourly readings
MONICAN buoys measure waves several kilometres offshore. At that point the swell already exists, but it can change significantly as it approaches Nazaré because of seabed shape, shoaling and the Nazaré Canyon. Offshore HMAX therefore does not directly represent the height of a breaking or surfed wave at Praia do Norte.
MONICAN values below are observations. Copernicus values are model estimates matched to the same UTC hour and buoy location. Only comparisons differing by 50% or less are included. This is a comparison filter, not a guarantee of model accuracy.

The season
When Nazaré wakes up
Historically, November to February is the peak big-wave season, with October and March as monitoring months when North Atlantic storms can still align with the canyon.

Historical seasonality indicates when large Atlantic swells are more common. It does not guarantee a big-wave event.
WHY NAZARÉ IS DIFFERENT
A meeting of ocean
and geology.
The canyon and the surrounding seabed help shape how Atlantic swell reaches this coast.

Forecasts without the noise.
We bring together swell height, period, direction, wind and ocean-model context to make Nazaré easier to read.
No hype. No invented wave heights. Just the signals the Atlantic is actually giving us.
Real data
Forecast models and ocean data. No fictional conditions to make the day look bigger.

Same Atlantic swell.
Different local response.
Adamastor preserves each forecast run and studies how Atlantic conditions evolve.
- Forecast history
- Every hourly forecast run is preserved for longitudinal analysis.
- Signal evolution
- Swell height, period, direction and wind are tracked across successive forecasts.
- Seasonal context
- Current conditions can be compared with the historical behaviour of each spot.
- Local response
- Building the evidence needed to understand how each surf spot responds to different Atlantic configurations.
