St. Lucia in October

we booked our honeymoon in st. lucia. does anyone know how the weather is in october. also can i swim in the water, is that a time for jelly fish. I heard that some people were taking out insurance in case of hurricanes, is this something I should consider

I'm going in August and staying at Sandals Grande St. Lucian. All Sandals resorts include a Hurricane Guarantee and will compensate you for your stay if there is a hurricane.

(It is important to consider insurance in case one of you gets sick or there is an emergency.)
