We're headed to Ocho Rios the first week of January. I'm looking at weather forecasts for next week and it shows a high of 77 degrees a couple of days, other days only 80 degrees. Has anyone recently returned from Jamaica (preferably the ocho rios area)that can say how the temps are during the day? Is it still hot when laying by the pool / ocean? Do I need to take anything long-sleeved for the evenings? I've been to Jamaica several times but not at this time of the year. Thanks.
