Conditions at Sultans in January
January: The Northeast Monsoon Grind
January is the full expression of the northeast monsoon. The waverose is dominated by ENE swell at 71.6 per cent, with the bulk of the energy in the 1.6-5ft (0.5-1.5m) range and a scattering of bigger 4.9-6.6ft (1.5-2m) sets. Average height sits around 3.5ft (1.1m), but the average period is only 6.7s, so it behaves like short-period trade-wind swell rather than a proper groundswell. The wind picture is the problem: NE and ENE directions combine for over 70 per cent of the observations, and the ideal W-NW offshore quadrant appears just 17 per cent of the time. That leaves Sultans' southeast-facing reef lumpy and textured for long stretches, with clean windows generally limited to brief northwesterly switches. Air temperature averages 27.2°C, water temperature is a warm 28.3°C, and precipitation is low at 1.93mm/day - dry, but not necessarily clean.
