The San Blas themselves are out of the hurricane zone but if you are coming from the U.S. , Bahamas, or western Carribean you will have some degree of exposure in the "zone" just when things are starting to "heat" up. Keep an eye on the weather and haul ass.
I'm planning on going through the canal (west to east) in June and would like to spend part of the hurricane season in the San Blas Islands and part of it in Cartagena. Then, in November, on to St. Lucia via the ABC's.
I would like to know if that's a reasonably safe (from tropical storms) and sensible plan.
