I'd say they're ok if you compare it to Australia or Hawaii for example. But there's definitely the ones that are more crowded, usually those considered "surf capitals" like maresias, florianópolis, garopaba, etc.
I think that fits perfectly Hive account@jasperdick, some waves are kept more secret by the locals and that's sure one rule to follow when posting them on social media. Maybe avoiding showing its accurate location, name or so.
For me the most important are the pictures ahaha And also, its not everybody that wants to paddle 2km into the sea to surf a shallow reefbreak when its big, so that kinda keeps the bigger crowd away.
Me and my friends are locals on these waves I present and we love to share it with old and new friends, so we're constantly taking new friends to check these out! Anyone here on the community who's down, just let me know! 🤙
