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.

July at Bathtub Beach is typically a very flat month for surfers, with an average swell height of only 0.3m and a period of 7.2s. The vast majority of waves (over 90%) are below 0.5m, coming primarily from ENE and E directions, with a few slightly larger waves (0.5-1m) making up less than 10% of conditions. Swells over 1m are extremely rare, occurring less than 1% of the time, and waves bigger than 1.5m are nearly nonexistent. Wind conditions are generally not favorable either, with ideal surf winds occurring just 1% of the time. The most common winds come from ESE, SE, and SSE at 10-20kph, which can create choppy surface conditions. Given these statistics, July is not a productive month for surfing here—expect very small, weak waves with onshore winds dominating. Only longboarders or beginners may find rare rideable days when ENE swells combine with lighter winds. Advanced surfers will likely want to seek other spots during this period.
