Fresh Juice in Season in March & Rum Punch Recipes???

Will be in Negril in March. What fresh juices will be in season and available on the beach? Would like to plan what I will have to buy at the grocery.

Also, anyone have a good rum punch recipe that is made with juices available in Negril that they would like to share?

Thanks!

orange juice, pineapple juice, light rum (overproof is always good), dark rum, squeeze of lime. When behind the bar I use a splash of grenadine for color. If not sweet enough make some simple syrup. equal parts of water and sugar cooked until dissolved. If you don't have a stove, I'm sure that water left out in the sun will get warm enough for the sugar to dissolve.

My wife and I drink overproof with equal parts of fresh pineapple, fresh orange and the store bought cherry juice.
