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.

December at Praia dos Molhes offers decent surf conditions with an average swell height of 1.4m and a solid period of 8.3s, producing clean, well-spaced waves. The swell is predominantly from ENE to SSE, with the majority of waves in the 1-2m range, peaking around 1-1.5m (12.7% from E, 9% from ENE). Larger waves (2m+) are less frequent but occur mostly from ESE to S directions. Wind conditions are variable, with only 17% being ideal (typically light offshore or sideshore ENE-NE winds under 20kph). However, moderate onshore winds (10-30kph) from NNE-SSE are common, which can create choppy conditions. Surfers should target days when winds stay light ENE-E or NE for cleaner waves. The spot handles smaller to mid-sized swells well, but larger swells may get wind-affected. Overall, expect rideable waves most days, but prime sessions require favorable wind alignment.
