yep, happens a lot in our neck of the woods during the monsoon season, luckily no one has been struck.
Years ago landing a jump the shock was big enough for my hand to jolt off the bar right in the middle of redirecting it after a decent jump. You can hear the arcing zaps as the board makes contact with the water!
It usually happens at the leading edge of a storm just before the rain buckets down,,,, especially if the wind suddenly changes direction and the temperature drops 10 degrees,,,, definitely time to come in. Once, a few of us had literally just landed the kites and just a few hundred meters away, a damn strike,,, a serious flash of light and instantly ionized the air,,,,crazy weird smell,,, bloody hell that was close.
Cheers,
