Located at or near the beach or seashore.
We had a wonderful time at the surfside picnic.
Surfside → The word is formed from "surf" (from Old English *syrf*, meaning the swell of the sea) and "side" (from Old English *sīde*, meaning the lateral part or edge). Together, these parts describe the area or location adjacent to the surf or waves of the sea.
Imagine being next to the waves ('surf') at the edge ('side') of the beach — that's what surfside means.
