What exactly might be on the offshore menu can be a little less predictable. Traditionally, albacore and bluefin reliably move into the range of one-day boats and private boats (loosely defined as 50 miles or closer) around July 4, when water temps reach the mid-60s, and then as the water warms up, they are replaced by other pelagic species, like yellowfin tuna, dorado and yellowtail. As this was written, summer 2010 had delivered a start-and-stop albacore and bluefin bite and a solid wall of cold, off-color water - referred to by skippers as the "green door" - that kept the tuna south and west of the Southern California coast. When the door opened up momentarily, boats enjoyed some epic but short-lived bites on longfins and mixed bluefin. San Diego long-range boats reported large schools of tuna down the Baja coast, which bodes well if conditions normalize and permit the usual northward migration patterns.
