Preguntas Frecuentes
Why do surfers and meteorologists measure differently?
Surfers measure face height (trough to crest), while meteorologists measure swell height (energy from the ocean). Face height is always larger, which is why 8-foot swell equals about 15-foot waves to surfers.
What is Hawaiian scale?
Hawaiian scale is one system for describing wave size, roughly half the face height. When Hawaiians say 6-foot, it means about 12-foot face height to California surfers.
How do I know which scale my forecast uses?
Check your forecast source details. US mainland usually lists face height, Hawaii uses Hawaiian scale, and NOAA uses swell height. This converter helps translate between all three.
