Loading the marine forecast…
Height alone is misleading. A metre and a half of swell at twelve seconds carries far more water behind it — and breaks with far more force — than a metre and a half at six seconds, even though both read the same in a forecast. What measures that difference is wave energy: what a whole wave carries per metre of crest, expressed in kilojoules.
It comes from E = ρg²/(32π) · H² · T², so it grows with the square of the height and the square of the period — which is why a long groundswell hits so much harder than a short windswell of the same size. As a reference, below 100 kJ it is small; 100 to 300 works for a longboard; from 300 kJ there is plenty of push for a shortboard; and past 1,000 kJ the sea starts to get serious.
At El Confital the historical mean is 308 kJ and one day in ten exceeds 680 kJ; the record in the series is 6,794 kJ. The most powerful month is January at 541 kJ, and the weakest August at 113. The forecast above gives the value for each slot.
If you prefer the unit used in oceanography, mean wave power here is 14.3 kW per metre of crest. It measures something different — energy per second rather than per wave — so the period counts for less.

Across the 271,752 hourly reanalysis records, 37.0 % of the swell reaching El Confital comes from the N. Median height is 1.66 m and mean period 8.5 s; one day in ten the sea tops 2.6 m.
Surfable sea — at least 0.8 m and an 8 s period — occurs 54 % of the time over the year, peaking in January (84 %) and bottoming out in July (5 %).
Wind is what separates a good day from a wasted one. At El Confital the swell arrives from the N, so the wind blows offshore — the one that grooms the wave — when it comes from the S. That happens 5 % of the hours in the year. Add 17 % of glassy hours, below 8 km/h, and the air is in your favour 22 % of the time.
Against you: 73 % of the time the wind blows onshore and messes the wave up. The most repeated direction of the year is NNE. On average there are about 2 hours a year with wind above 40 km/h, concentrated in the winter storms.
Both roses carry a marker on the rim showing what suits this spot. El Confital faces N (10°), so clean swell only enters from WNW to E — the blue arc. The dominant swell direction is N, with 37 % of the hours in the year, and it falls squarely inside that window, which is why the spot is rarely flat.
Wind works the other way round: the good one blows from land to sea, holding the wall of the wave up and grooming it. Here that is the wind from SE to WSW, the green arc. The red one is onshore, arriving from sea to land and messing up the surface: NW to ENE. The most frequent wind of the year is from the NNE.
Each spoke points to the direction the swell or wind comes from, and its length is the share of hours. The scale is square-root, as is standard for roses, so small sectors do not vanish next to the dominant one.
El Confital, on the tip of La Isleta in Las Palmas, is a long, fast right over a rock bottom that on its best days gets compared to Indonesian waves, and earned the Canaries the nickname of "the European Hawaii". It sits literally next to the city, so the peak fills the moment a northerly swell arrives.
Sea temperature forecast for the coming hours: –.
The statistics on this page are not estimates: they are computed over 271,752 hourly records from the ERA5 reanalysis between 1995-01-01 and 2025-12-31, 31 full years. ERA5 is the atmospheric reanalysis of the European Centre for Medium-Range Weather Forecasts, and its ocean component reconstructs the state of the sea hour by hour by combining the wave model with every available observation.
Wave data comes from the ERA5-Ocean model and 10-metre wind from atmospheric ERA5, both served by Open-Meteo. The next seven days come from the operational marine model, which is a different thing: a forecast, not a record.
Two limits worth keeping in mind. First, the model describes the open sea, and what the wave does when it meets the specific bottom at El Confital — the bank, the reef, the tide — is not in these numbers. Second, model resolution is several kilometres, so on deeply indented coastlines the grid point can sit some way from the peak. Always check the local report before paddling out.
