What scoring scale do I use, and when does a wave count?

Under the SSA Rulebook 2025:

• Score every wave ridden by every competitor from 0 to 10, in one-tenth increments.
• A surfer's best two waves count; there's no maximum wave count.
• To be scored, the surfer must be clearly in possession of the wave and on the wave face, making a movement to stand with hands off the rails. This applies during the heat and at the end.
• The heat ends when the first finishing horn is heard by the Head Judge, who then tells the judges that no more rides are to be scored.

The same scale is used for shortboard, longboard and SUP. The commentator may not announce scores until all judges' scores are entered.
