I went last year in Mid November. Went with an outfit called Baja anglers.
They have an office in the Marina, there are a few others there as well.
Caught a few Striped marlin and some small Rooster fish. They will provide you with Fly fishing gear if you want to try catching a Marlin on the fly.
Pretty good outfit, they have had a few articles in Marlin magazine.
Here's a post from last year

Should be pretty good fishing, they just had the Tournament a few weeks ago. Sounds like there was lots of fish.
Here's a link on the tournament

Give the buggy's a try over at Wide Open Baja. They are a blast.
