Conditions at Inch Reef in January
January: Deep Winter Power
January is a heavyweight month. The average wave height sits at 6.2ft (1.9m) and the average period at 12.7 seconds, so this is proper long-period North Atlantic groundswell. The swell rose is dominated by W (28%), WNW (22%) and WSW (13%) energy, with a significant chunk of waves in the 5-8ft (1.5-2.5m) range. These are powerful, heavy lines, but because Inch Reef faces SSW, only the more southerly components of that window really line up; the pure W/WNW swells come in more cross and need the right tide to show their best shape.
The wind story is less pretty. S through W are the dominant onshore directions, and the ideal offshore N/NNE/NE/NNW flow is present only about 20 percent of the time. When a cold front clears and the wind snaps around to a chilly north or northwest, the reef produces some of the thickest, most pitching winter waves of the year. With air temperatures around 7°C and water temperature stuck at 8.1°C, you will earn every session.
