I'm planning a trip to Belize this winter. How is the weather in January? If it's not that warm, when is the best time to go?

I'd like to know more about January weather myself. Someone on this board told me January is nice and there maybe a little bit of rain. I am going in January as well. I was there in March before and the weather was good at that time. We had no rain the whole week we were there. The temp was in the 80s with a breeze most of the time. I wore long sleeves at night but I get cold easily.
