Online timer for 39 seconds

While the board gets its rinse after a surf, waiting through thirty-nine seconds keeps the pause simple: water runs over the rails, deck and fin area while salt and loose sand wash away. There is no need to squeeze another job into the interval; standing by also makes it easier to notice when runoff looks clear or the board needs turning.

With wet hands, a towel and a sandy board competing for attention, accidentally closing the tab is quite possible. The countdown may stop or disappear when its tab or browser closes, so keeping the screen open avoids losing track midway through the rinse. If the page does vanish, the visible amount of salt or sand is a more useful guide than guessing how much time remained.

At a shared beach rinse tap or beside mates packing boards into the ute, a loud finish can catch people nearby off guard. Keeping the phone close and using a restrained volume lets the signal mark the end without carrying across the car park. If the board still feels gritty, continuing briefly and stopping by observation makes more sense than treating the sound as a rigid cutoff.
