Hello, what are the typical conditions for the Keys (Key Largo and Big Pine Key specifically) during mid-december. Looking for typical water temps (top and bottom), viz, currents, and surface conditions (wave heights).

Thanks!
 
Water temps should be in the low to mid 70's. Viz averages 50' year round in the upper Keys. Currents can be brutal, other times there won't be any current. Some sites are more prone to currents than others. Seas will vary from glassy to stay in port.

I agree with what Walters' post says.

Wave heights vary depending upon wind conditions, obviouisly. That time of year we sometimes get cold fronts moving through & the wind associated with these fronts cause wave heights that sometimes prohibit dive boats from going out. (Prudent Captains).

Prepare for marginal sea conditions and take an appropriate seasickness preventative if conditions warrant. Also have "Plan B" in place in case wind & seas make diving not an option. There is really no decent shore diving down here as the reefs & wrecks are several miles offshore.

Check out NOAA's historical data for Molasses Reef here:

As Jim suggests, prepare for bouncy conditions, and have a back-up plan in case a trip gets blown-out (the Everglades are great this time of year). Bring a drybag packed with a towell, fleece (sweats), and a waterproof windbreaker or dive parka for the boat ride home. You might even get lucky, and have a day or two like TODAY! Between winter cold fronts, Keys dive conditions are phenomenal. Enjoy!
