Conditions at Sanur in January
January: Prime Wet-Summer Groundswell
The northwest monsoon dominates January, and it is a standout month for Sanur. While the ideal NE-ESE swell never shows up in the statistics, the practical reality is that 100% of the wave energy arrives from the SSW/SW/WSW quadrant, wrapping into the east-facing coastline. SSW accounts for 35.7% of the swell and SW for 47.4%, producing a healthy 5.6ft (1.7m) average at a long 12.2-second period. The bulk of the waves fall in the 3-6.5ft (1-2m) fun-to-pumping range, with meaningful 6.5-8ft (2-2.5m) sets thrown in. Winds are your friend this month: W winds blow 40.8% of the time, while WSW and WNW add another 29%, giving Sanur a clean, groomed offshore flow. Air temperatures hover near 25.5°C with high humidity and about 10mm/day of rain, while the sea sits at a warm 29.1°C. When break clouds clear between showers, Sanur can be truly excellent.
