Both caves open on the east wall of the Punta Giglio promontory, which sits on the NW shore of the Gulf of Alghero, so the headland mass fully blocks the entire landward W-NW-N arc, including the prevailing NW Mistral and Tramontana. The exposure is the SE-through-SW window that looks down the open, SW-facing mouth of the gulf, where a Scirocco from the SE and, above all, a Libeccio from the SW build the largest wind-waves and can push swell straight onto the wall. Being microtidal Mediterranean with no ocean groundswell, conditions are usually calm, but surge inside the shallow tunnels can amplify sharply on a windy SE or SW day.
