Praia do Silveira - surf spot statistics

Praia do Silveira, Brazil, offers surfable waves year-round, but the conditions vary significantly by season. The best months for surfing here are generally from May to September, when ground swells become more dominant, providing cleaner, more consistent waves. May and June stand out with ground swell probabilities at 42% and wind swells dropping to 57-58%, resulting in better-quality waves. During this period, mean swell sizes range between 1.6m and 1.7m, offering solid overhead conditions on good days. Wind conditions, however, remain somewhat challenging, with favorable winds only around 25-26% of the time in May and June, though this is still better than other months. July and August see a slight dip in ground swells (34% and 31%) but maintain decent swell sizes (1.7m). September has the largest average swell (1.9m), but wind conditions worsen, with bad winds occurring 86% of the time. The worst months for surfing are from October to February, when wind swells dominate (81-84%), leading to choppier, less predictable waves, and good wind conditions become rare (13-21%). Swell size in these months averages around 1.4-1.7m, but the high frequency of poor wind conditions makes sessions less ideal. For surfers seeking quality waves, mid-year (May to August) is the prime window, despite the persistent wind challenges. Early morning sessions or sheltered spots nearby may help mitigate the often onshore winds.
