Conditions at Nusa Dua in January
January: Monsoon Gold at Nusa Dua
January is the heart of the northwest monsoon, and Nusa Dua wears it well. With an average swell height of 5-6ft (1.5-1.8m) and a 12.4s period, the ocean is pumping out powerful, rideable surf. Nearly half of all swell energy arrives from the SW (47.4%), with another 35.7% from the SSW and 11.3% from the WSW - exactly the window that lights up these SE-facing reefs. The real winner, however, is the wind: ideal conditions 63% of the time. W and WNW winds dominate the rose, blowing offshore/cross-offshore and keeping faces clean. Air temps sit near 27.8°C with water at 29.1°C; expect regular tropical showers (9.5mm/day). Catch a pulsing SSW swell between rain cells and you'll find peak-season Nusa Dua at its best.
