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.

Bathtub Beach in February offers relatively small but rideable surf, with an average swell height of 0.6m and a decent period of 8.6s, suggesting clean, organized waves despite the modest size. The dominant swell direction is ENE, contributing the highest percentage of waves in the 0.5-1.5m range (28% at 0.5-1m and 6.4% at 1-1.5m). This means the best conditions arise from easterly swells, which align well with the beach's orientation, but larger waves (1.5m+) are rare—only 2.5% of the time. Wind conditions are a mixed bag, with ideal offshore winds occurring just 10% of the time, mostly from westerly directions (WNW, NW), which could clean up ENE swells. However, prevailing easterly winds (ENE, E) are more common, often blowing onshore at moderate speeds (10-30kph), potentially creating choppy conditions. Surfers should target days with ENE swell and lighter winds or NW wind shifts for the cleanest waves. Overall, February is inconsistent but workable for intermediate surfers on smaller days, with occasional better sessions when wind and swell align.
