Bathtub Beach - surf spot statistics

Bathtub Beach in the United States offers variable surf conditions throughout the year, with the best months for surfers typically occurring in the late fall and early winter. November stands out as the most favorable month, featuring a higher percentage of ground swell (17%) and wind swell (58%), combined with the lowest likelihood of no swell (25%). The mean swell size peaks at 0.8 meters, and wind conditions are relatively better than in other months, though still challenging with 89% unfavorable winds. October and December also provide decent conditions, with October showing a good balance of ground swell (16%), wind swell (52%), and a mean swell size of 0.7 meters, while December mirrors November with 19% ground swell and 0.7-meter swells. Winter months like January and February see moderate ground swell (14%) but suffer from poor wind conditions (88-90% unfavorable), though the swell size holds at 0.6 meters. March sees a slight improvement with 19% ground swell and 0.7-meter waves but remains hindered by very high bad wind percentages (91%). The spring and summer months, particularly from May through August, are the least optimal, with minimal ground swell (0-9%), high percentages of no swell (52-92%), and very poor wind conditions (94-99%). September shows a slight recovery as fall approaches, but it’s not as consistent as the late fall and early winter months. Overall, surfers will find the most reliable waves from October through December, with November being the standout month despite the persistently challenging wind conditions.

January at Bathtub Beach offers relatively small but rideable conditions, with an average swell height of 0.6m and a decent period of 8.8s, suggesting some energy in the waves despite their modest size. The dominant swell directions are ENE (peaking in the 0.5-1m range at 24.96%) and NE (11.39% in the same height range), providing the most consistent surf. Larger swells (1.5-2m) are rare but occasionally come from the ENE direction (1.25%). Wind conditions are less favorable, with only 12% of the time being ideal for surfing—typically when lighter winds (0-20kph) align offshore or cross-shore. Stronger onshore winds from the N-NNW sectors are more common, which can degrade wave quality. Overall, expect smaller, manageable waves with occasional clean conditions, best suited for longboarding or relaxed surfing when winds cooperate.
