January and the New Year usher in amazing diversity of underwater options in the Biminis. Average water temperatures are mid 70s. Only divers from the extreme north are getting by without at least a full 3mm wetsuit. I am currently using a 5mm suit with gloves and a hood.
Cooling temperatures above and below the water mean algae cannot grow, and the typical dry season beginning means not a lot of run off. These factors translate into crystal gin clear water. Visibility is continually at or more than 100 feet. Northerly cold fronts begin to bring strong winds on occasion, but many great days on the water remain to be had this month.
Many migratory species of pelagic fish are passing through Bimini in the beginning of the year. Large schools of wahoo and cero mackerel are common on our deeper drift dives, such as Pinnacle Leap and the Nodules. Greater hammerheads and bull sharks sightings are becoming almost common place this month. Nassau grouper are in one of the peak months of their spawning, and can be seen in large numbers on sites of Cat Cay, such as Tuna Alley and the Victories. Do not be tempted by their uncommonly brave behavior this month, remember that catching Nassau grouper by any means is prohibited this month.
January often seems to have plenty of days with a southern current, which is the opposite of the traditional northerly “Gulf Stream” influenced currents we usually have. This can often make a drift dive, like Tuna Alley or the Victories you’ve done many times before, seem completely new. By getting the chance to cruise the opposite direction from our usually starting points, it is almost like a whole new dive site!
So get out there and take advantage of all the unique and exciting things happening above and below the ocean in Bimini.
