January: Northeast Monsoon Power
January is the heart of the northeast monsoon, and the numbers show all the hallmarks of a high-energy trade-wind month. Average swell reaches 1.1m (3.5ft) with a punchy 8.3s period, but ENE swell dominates the wave rose at 61.5%, followed by NE at 29.0% and E at 7.9%. For a southeast-facing harbour that performs best on S/SW/SSW/WSW swell, this is mostly the wrong kind of energy--large enough to look promising but too shadowed and cross-shore to break with real quality.
Winds are locked into the NE/ENE trade pattern: 39.8% from NE and 29.6% from ENE, with most readings in the 10-30kph range. These are cross-shore/side-offshore winds, not the clean N/NW offshore flow that puts Virac into its best form. Ideal wind is present 23% of the time, usually in short bursts when the monsoon surge shifts to a N/NNW direction. With air temperatures around 25.9C, water at 27.3C, and 11.71 mm/day of rain, January is a month of intermittent windows rather than all-day perfection.
