Wind makes or breaks it, bru. Offshore (blowing land to sea) grooms the faces clean and glassy — lukka. Onshore chops it all into mush. Under about 10 km/h it hardly matters — basically glass.Wind↓11 km/h NNECross/Onshore
1.4m @ 10s E reads as: a 1.4 metre swell, 10 seconds between each wave, marching in from the E. The @ is just "at".
Period is the secret, boet: 12s+ is proper groundswell — organised lines with real punch. Under 10s is local windswell that folds quick. Same size, longer period = way more klap.
Two numbers, two different things. The metres is the swell way out at sea. The feet is the wave face you'll actually be looking at when you paddle out — measured trough to crest on the side you ride, the way Surfline and every SA beach report calls it. It is not the old Hawaiian back-of-the-wave scale, which reads about half.

Pushing in or draining out, and when it turns. Most banks have a favourite tide — right tide and the spot comes alive, wrong tide and it goes fat or dumpy. Time your session, china.TideMid / Falling — Low in 3h 31m
