I'm not an expert - I don't think I'm even a competent amateur - but I presume landing options are limited due all manner of factors, especially in a lagoon, and most landings are somewhere near parallel to the beach / shore, which is invariably perpendicular to prevailing winds. I might be wrong but I suspect that might be the reason for the crosswinds.
Sorry if that sounds like an egg sucking response - not intended to offend - just a guess at the reasoning for twobags statement
