Conditions at Bathtub Beach in January
January: Midwinter Momentum
The new year opens with Bathtub Beach at its most consistent. Average surf heights sit at 4ft (1.2m) with a 7.7s period, and the swell window is dominated by NNE, NE, and ENE directions that add up to over 45 percent of the total. These are not just short-period windswell; low-pressure systems spinning up along the southeastern seaboard and mid-Atlantic push punchy, rideable energy toward the east-facing reef. The key is wind. January offers the highest offshore wind frequency of the year at 29 percent, with NNW/NW and SW/WNW flows lining up behind cold fronts. On those days, the west winds groom the NE swell into clean, hollow walls. Water temperatures are around 22.5°C and air temps average 20.2°C, so conditions remain pleasant even in deep winter. When the wind does flip E or SE, expect onshore chop and a much more difficult session.
