Re wind in Bocas/Panama:
Western Panama, including Bocas, is almost always light and variable. Except Bocas can get a light to moderate sea breeze in the afternoon.
The NE Trades only fill in seasonally in Panama and then only in Eastern Panama...so no
Trade Wind sailing to or in Bocas. The seasonal Trades fill in around January till May and then go light for the summer months. They only fill in from about Colon to the east. Which means Bocas gets none, but the the amazing San Blas islands get full on
Trade Winds thru the season.
