The summary: Low tide is at 5:33 AM (race starts at 7:15 AM) flowing back to a late morning high tide. Swell is between two and three feet (much smaller than Strawberry Fields a few years ago) out of the SSW.
Here are activity logs (including maps and elevations) for the bike and run course from the 2006 Nautica Malibu Triathlon over at MotionBased. The bike course is much hillier than I expected (miles 9 to 12 gain 200 feet). That’s a similar gain to the hill up the backside of the Rose Bowl — it gains 100 feet in a little less than 1.5 miles. Glad to see the run is pretty flat.
There are two loopy go-under-PCH turnarounds during the bike section of the Malibu Triathlon. The course map is not very detailed so I tried to put the plot the course using Google Maps… results below.
The first is at the very beginning and gets you out of the parking lot and going west on PCH.
The second is just over half way and gets you going east again on PCH:
