Rain days: days with 1 mm or more in the ERA5 grid cell (about 30 km across); over tropical seas it counts more light-rain days than a local rain gauge would. Calm days: waves under 1.5 m and wind under 25 km/h. Storm risk: share of years with a named storm within 250 km that month (– means under 5%).
