Where do grunions spawn?

Grunions spawn on sandy beaches along the coast of Southern California and Baja California, particularly during spring and early summer. They typically come ashore at night during the high tide to lay their eggs in the sand. The eggs are then covered by sand and will hatch after a few weeks, coinciding with the next high tide. This unique spawning behavior makes grunions a fascinating subject for both marine biologists and beachgoers.
