Conditions at Kapu Beach in January
January: Northeast Monsoon Gold
January is one of the cleanest months of the year at Kapu Beach. The northeast monsoon is at full strength, and that means a steady supply of offshore winds from the northern/eastern quadrant around 46 percent of the time. Most of the swell arrives from the W/WNW/NW window - WNW leads the pack with 26.9 percent of the total, followed by NW at 22.8 percent and W at 18.4 percent - so the beach is well exposed to the dominant energy. Average swell height sits at 2-3ft (0.7m), with the majority of waves in the 2-3ft (0.5-1m) range and a scattering of 3-5ft (1-1.5m) sets from the NW.
The 9.4s average period means the waves are rideable and punchy rather than overly powerful, but the combination of light offshore flow and small, clean swell makes it a fantastic month for groveling and longboarding. Water temperature is 28.5°C, air temps sit around 25.9°C, and rainfall is negligible at 0.05 mm/day. It is the kind of warm, tropical consistency that keeps the lineup friendly.
