Jamaica is aligned from East to West. The trade winds at this time of the year blow from the North East.
Portland parish (Port Antonio) get the brunt of the wind and seas.
As you go West the effect is reduced as you go more to "leeward"..
Duncans Bay is tucked in bay that's protected from whats left coming the East. Most times not much sea.
Negril is as far "leeward" as you can. Totally different sea state...
