How is the weather in Jamaica during late September early October?
It’s hot and at the moment the entire Caribbean area is subect to scattered thunderstorms or showers because of a weather system. If you look on this link you’ll see what I mean — the red blob. http://www.nhc.noaa.gov/ But it’s also clear from the map that once the red blob has passed over the area (and its forecast to travel further north), the weather is going to be fine, because there are no other weather systems to worry about. Take lots of sun screen and stop fretting.
