Guarda do Embau - surf spot statistics

Guarda do Embuau is a beach break that primarily receives wind swells, with ground swells making up a smaller portion of the swell regime. The best months for surfing here are typically from May to August, when ground swell contributions increase slightly, averaging around 26-34%, compared to the rest of the year where wind swells dominate (62-88%). During these months, wind conditions are also more favorable, with good wind days occurring 32-37% of the time, peaking in June. While swell size remains relatively consistent throughout the year (1.1-1.4m), the combination of slightly cleaner conditions and marginally increased ground swell makes mid-year the most reliable period. From September onwards, wind quality deteriorates significantly, with bad wind conditions rising to 79-81%, making it less ideal. The early part of the year (January-April) sees a similar issue with higher frequency of onshore winds (up to 77% bad wind days in January), though March and April offer a slight improvement. Overall, May to August provides the most balanced conditions, with a better mix of swell and manageable winds, though surfers should still expect predominantly smaller, wind-driven waves with occasional ground swell influence.

March at Guarda do Embaú offers solid surf conditions with a mix of rideable swells and variable winds. The average swell height is 1.2m with a decent 8.8s period, providing consistent, well-formed waves. The dominant swell directions are from the ESE, SE, and SSE, where most waves fall in the 1-1.5m range, though 2-2.5m waves occur occasionally, offering more powerful sessions. Smaller swells (0.5-1m) are frequent, making it suitable for intermediate surfers, while bigger sets (1.5m+) add challenge for advanced riders. Wind conditions are less reliable—only 28% of the time are they ideal, with the best scenario being light offshore (W-NW) or calm winds. However, NNE-NE winds (10-20kph) are common, potentially creating choppy conditions. The strongest winds (20-30kph) usually come from N-NNE, which can degrade wave quality. For the best sessions, watch for ESE-SSE swells paired with light W or NW winds. Expect a mix of playful and punchy waves, but be prepared for some wind-affected days.
