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.

April at Bathtub Beach offers mostly small but surfable conditions, with an average swell height of 0.6m and a decent period of 8.8s, suggesting relatively clean, though not powerful, waves. The dominant swell direction is ENE, contributing the largest share of waves, particularly in the 0.5-1.5m range (around 38% combined for 0.5-1m and 1-1.5m). This alignment often produces rideable peaks, though expect smaller, more frequent waves rather than overhead sets—only 1.5% of swells exceed 1.5m. Wind conditions are less favorable, with just 8% of winds being ideal (likely light offshore or cross-offshore). Easterly winds (E-ESE) prevail at 10-30kph, which can create chop, especially as they account for nearly 20% of wind occurrences at those speeds. Surfers should target early mornings when winds are lighter or days with ENE swell and minimal SE wind interference for the cleanest sessions. Overall, it’s a month for loggers or small-board riders rather than high-performance surfing.
