We were in Negril last November, the last week of the month and the weather was BEAUTIFUL. It is a great time of year to be there, still plenty warm, a light afternoon shower for about 30-45 minutes and then just wonderful in the evenings. You will love it.
We honeymooned at CTI last November and the weather was great. There was some rain a couple of days as the result of a distant offshore storm, but that can be expected in the tropics. Other than that, it was great. We slept with our balcony doors open every night, going to sleep to the sound of the waves and being serenaded by the tree frogs.
BTW - we're going back this November, this time to Negril.
No worries! We were at CN last November and the weather was absolutely beautiful! There were only two short afternoon showers and lots of sun. We loved it so much that we plan to return in November of 2011! Have fun!
