What is the Palata index?

Surfers look for waves. Our index looks for as few as possible: from 0 (stormy) to 10 (mirror-flat). It weighs wave height, wind waves, the wind right now and the wind over the past ten hours. High waves cap the score even when the wind has died. The forecast is a model ensemble via Open-Meteo; on the central coast the app also shows the live ISRAMAR Hadera buoy.
