Conditions at Sanur in May
May: Big Southern Groundswell, Onshore Trades
May is where Sanur's seasonal window slams shut. The average swell height jumps to 6.2ft (1.9m) and the period lengthens to 13.9 seconds, with SSW delivering 44.8%, S 31.0% and SSE 11.4%. More than half of the waves fall between 5-8ft (1.5-2.5m), and there is even a hint of XL juice above 8ft (2.5m). But the southeast monsoon has arrived: ESE wind blows 57.3% of the time, SE 18.7%, and E 14.8%, while offshore W-WNW flow nearly disappears. Ideal wind is just 3%, so the long-period swell is chopped, textured and cross-shore. Sea temp drops to 28.8°C and rainfall to 2.40mm/day-dry season is beginning. The power is there, but the quality is not.
