Having done this route I can honestly say that the Rains guide was at the bottom of the pile as far reference tools.
A good weather
program ( we used the GRIB file weather program downloaded by SSB) I am hoping you have a good SSB
The first problem area you will encounter is Punta Mala Panama
,from there it is its pretty much doldrums until you reach the Costa Rica
Papagayo area between Costa Rica
. The winds outside of San Juan
del Sol gave us more of a challenge than the T-Peckers.
WE made a mistake of hugging the coast in an effort to reduce fetch but the effect of the excellerated winds from the steep coastal mountains gave us a run for our money
Unpredictable gusts were the biggest challenge.
Check the weather and pick your window. We waited in Barillas Marina El Salvador for a weather window and basically had a flat crossing into Mexico
