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.

In August, Guarda do Embaú typically offers surfable conditions with an average swell height of 1.3m and a decent period of 9.2s, indicating consistent, well-spaced waves. The swell direction is predominantly from the SE to SSE sectors, contributing the highest frequency of rideable waves, with a notable percentage in the 1-2.5m range (around 20-30% of the time). ENE and E swells also provide some decent-sized waves, though less frequently. Wind conditions are favorable for surfing 28% of the time, with lighter winds (under 20kph) from the N, NE, and SE directions being most common. However, stronger winds (20-30kph+) from the N, S, and SSW sectors can create choppier conditions, especially when paired with larger swells. Overall, August delivers a mix of workable surf with occasional clean sessions, particularly when winds align offshore or remain light. Intermediate to advanced surfers will find the best opportunities on days with SSE swells and favorable wind alignment.
