January: Offshore Winds, Flat Micro Waves
January sets the tone for the dry season: wind is not the problem, but swell energy is. The average wave height is a tiny 0.3m (around 1ft), and over 94% of the wave spectrum sits below 0.5m. The swell is split between a background SSW/SW component (SSW 40.9%, SW 12.8%) and local N/NNE windswell (N/NNE combined 25.1%), but every sector is predominantly in the micro bucket. The 9.4s average period keeps the energy punchy and rideable once it is above waist high, but that rarely happens. Winds are overwhelmingly offshore: N, NNE, NE and ENE sum to nearly 67%, with the strongest pulse coming from the NNE and N directions in the 10-30kph range, so the surface is often clean and groomed. With 0% ideal surfing conditions, January is a classic flat, glassy month for Isla Chepillo. Air temperatures average 26.5°C with 0.65mm/day of rain, and water temperature sits at 26.5°C.
