Praia dos Molhes - surf spot statistics

Praia dos Molhes in Brazil is primarily a windswell-dominated spot, with ground swells making up a smaller portion of the swell mix. The best months for surfing are typically from April to August, when ground swell contributions increase to around 29-38%, improving wave quality. During this period, mean swell sizes hover around 1.5-1.7 meters, offering more consistent and slightly larger waves. Wind conditions are less favorable year-round, with good winds occurring only 20-27% of the time, peaking from May to July. However, even then, bad wind conditions still dominate (73-77%). September and October see the largest mean swell size (1.6-1.7m), but wind conditions worsen significantly (only 14% good winds). The worst months are January, February, November, and December, where ground swells drop below 15%, windswells dominate (85-87%), and bad wind conditions are most persistent (80-87%). Overall, mid-year (May-August) offers the best balance of swell size and slightly better wind probabilities, though surfers should expect frequent onshore wind challenges. Early mornings may provide cleaner conditions before winds pick up.

In September, Praia dos Molhes offers decent surfing conditions with an average swell height of 1.7m and a solid period of 9.2s, indicating well-organized, powerful waves. The dominant swell directions are ENE, E, and SSE, with a significant portion of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. While ENE swells (7-9%) and E swells (6-10%) provide consistent head-high sets, SSE swells (8-13%) occasionally bring larger, more powerful waves for those seeking a challenge. However, wind conditions are less favorable, with only 14% of the time offering ideal offshore or light cross-shore winds. The predominant NE/ENE winds (10-30kph) often create choppy or cross-shore conditions, reducing wave quality. Wind shifts to S/SSW may occasionally clean things up, but strong onshore NE winds (over 30kph) are common, affecting surfability. For best sessions, target days with ENE/E swells and lighter SSE winds—early mornings may provide cleaner conditions. While September isn’t the most consistent month here, it delivers rideable waves, especially for surfers comfortable in shoulder-high to overhead surf with occasional chop.
