Spiaggia delle Sirene is a surf break tracked live by Surf Glyph. The report above turns the swell model — wave height, period and direction — plus wind and tide into a single glyph score, so you can tell at a glance whether it's worth paddling out.
Early morning, before the wind comes up. Aim for a light offshore around dawn on a mid-to-low pushing tide with a clean groundswell — that combination produces the cleanest, most makeable peaks.
