Sea state at Bouri: wave height exceedance by month

Bouri lies in the Mediterranean at 34.01° N, 12.47° E. Significant wave height there exceeds 2 m about 6.5% of the time across the whole year, roughly 2.0 days a month on average. The roughest month is January, with a mean significant wave height of 1.3 m and seas above 2 m about 15% of the time; the calmest is July, with a mean of 0.6 m and about 0.6% of the time above 2 m. Waves above 4 m occur about 0.1% of the time.

Wind at 10 m across the year: typically 6.0 m/s (12 kn), top 10% above 10.2 m/s (20 kn). Monthly means run from 4.6 m/s in August to 7.2 m/s in December.

Weather windows: a typical month fits about 28 separate 24 h periods with significant wave height below 2 m, fewest in January (about 25). Periods do not overlap, so a 30 day month holds at most 30.

Data basis

Data basis: WAVERYS wave reanalysis (Copernicus Marine) + ERA5 wind, 1980-2023, 3 hourly. Data point 34.00° N, 12.40° E (0.2° grid), 7 km from the named position, 128,568 samples. Values are for the nearest grid cell and are not interpolated.

Generated using E.U. Copernicus Marine Service Information: WAVERYS global wave reanalysis [1980-2023], 3 hourly significant wave height, peak period and direction. Wind statistics from the ERA5 reanalysis (Copernicus C3S) on its 0.5 degree grid (wind, direction rose, diurnal cycle and ENSO split 1980-2024). Neither the European Commission nor ECMWF nor Mercator Ocean is responsible for any use of this information.
