Conditions at Yo-Yos in January

January: Heart of the West Monsoon

January delivers a steady conveyor of SSW and SW groundswell, with 42.4% of waves coming from the SSW and 56.0% from the SW. The average swell height is 1.3m (about 4-5ft / 1.2-1.5m) and the period is a solid 12.6s, giving the peaky reefs an abundance of power and shape. The wind regime is largely influenced by the monsoon trough - it swings between W and WNW much of the time, but when the pressure relaxes the offshore N to NNW breezes kick in, producing ideal conditions 41% of the time. With the water at a warm 29.3°C and air at 26.6°C, the wet season (7.94mm/day) is in full force, yet the surf remains highly rideable. Expect clean, fun-sized waves with the occasional larger set, especially on the dawn glass-off.
