The shorebreak when it is on can be a kite killer. So the less time you spend around it the better. Where I see a lot of people making a mistake is when they get out of the water. What you need to understand is speed is your friend. What I mean by that is not that you fly as fast as you can onto the beach as that can be dangerous. BUT you do not want to stop and then try and body drag through the surf as the chances of a shore break giving you a beat down are far higher.
My advice is try to time it! So stay on your board – slow down so that you are the same speed as the wave and then come through on the back side of a wave. SO as the wave breaks and rolls up onto the beach you can ride up on this. It is normally 30cm deep which is deep enough to kite. Then as it starts to drain flick the board off your feet onto the dry sand.
Make sure that your kite stays in front of you and slightly higher so that it is not pulling too fast. Make sure that you keep your bar more de-powered so that if you do make a mistake then you are not ripping on the bar. I would actually go as far as to say that you should actually just let your bar go if you do get milked as more times than not the guys will pull their back hand and cause the kite to fly back through the power zone which can flick them onto the sand!!
Check this video below and notice how long he is in the shore break he gets out OK but things could have gone wrong!
HOPE THAT HELPS AND REMEMBER IF YOU ARE NOT SURE THEN RATHER DON’T GO!!!
