How this was measured

Every number on this page comes from four years of Open-Meteo marine and ERA5 reanalysis at a fixed point in this sea area, aggregated by calendar month. A month is called easy, mixed or hard by how many of its days are genuinely comfortable to be out on — not by a single day’s safety verdict, which classifies most days in most months the same way and tells you nothing about the year.
