Talking to Bill down at Oceanside and he said this weekend is supposed to see grunion. Not sure the dates for other beaches but generally they're pretty much the same at most SoCal beaches.
Remember that when the grunion move into the beaches they are usually followed by both halibut and bat rays. Of course he said it's also supposed to rain Wed-Fri so that might put a damper on some. And, even when there are predicted runs the grunion don't always show up where expected. I remember many nights when I was young and waiting on beaches for the grunion to show up. Sometimes they did and sometimes they didn't.
