January: Deep Wet Season Grind
The northwest monsoon is in full swing, and the average swell is 5ft (1.5m) with a period of 12.1s, putting most waves in the powerful long-period category. The swell rose is loaded in the right directions: SSW contributes 37.5 percent, SW 27.5 percent, WSW 21 percent and S another 3.5 percent. Much of this arrives in the 3-5ft (1-1.5m) range, with a healthy 5-6.5ft (1.5-2m) component from WSW and SW. There is genuine Indo groundswell moving through.
Wind is the weak link. WNW flow dominates at 26.4 percent, W at 19.9 percent and NW at 10.5 percent, putting a cross/onshore bump on the south-west-facing lineup. WSW/SW/SSW/S flow adds further chop, and ideal wind windows sit at just 23 percent. With around 9.5mm/day of rain, air temperatures near 27.4C and water at 29.0C, this is a warm, wet, sometimes lumpy month that still offers the occasional clean tide change.
