Conditions at Uluwatu in May
May: Full Groundswell Mode
May is where the dry-season swell machine hits its stride. Average height climbs to a solid 6ft (1.9m) and period lengthens again to 14.1s. The direction mix is broad but powerful: SSW (44.8%), S (31.0%) and SSE (11.4%) combine to put most energy in the 5-8ft (1.5-2.5m) range, with 0.4% pushing over 8ft (2.5m). On the wind side, the southeast trades are fully established-ESE is 55.4%, SE 17.1%, E 17.5%-and ideal surf wind reaches 61%. Those trades can blow fresh, so look for more exposed breaks to be a little textured, but Uluwatu's reefs still handle it well. Air temps 27.5°C, water 28.8°C, rain a minor 2.22 mm/day.
