December in Isla Fuerte means festive high season, book ahead. The water stays warm and inviting all year in this corner of the Colombian Caribbean, and each month has its own character underwater. Here is what to expect if you are planning to dive with us in December, and how to make the most of it.
Water and weather
The sea temperature holds between 27 and 29°C throughout December, so a rash guard or a thin 3mm wetsuit is all you need. There is no cold season here, which is part of why Isla Fuerte is such comfortable diving.
In December the surface conditions are typically festive high season, book ahead. Skies are often bright and the sea settles into an easy rhythm. Our guides read the day each morning and choose the sites that match the wind, swell and your level.
Visibility and what the diving is like
Visibility in December is generally good, with clear stretches between passing weather. The sheltered reef sites stay enjoyable even when the open water gets a little more movement, so there is always somewhere excellent to dive.
What you might see
The reef is alive year-round. In any month you can expect turtles grazing the shallows, schools of grunts and snappers over the coral, moray eels tucked into ledges and, with luck, an eagle ray gliding past. Nurse sharks rest under the ledges by day.
Explore where each animal turns up on our interactive dive map and tell us what you most want to see.
Planning a trip in December
December is festive high season on the island, so lodging and boat spots fill early. Book well ahead to secure your dates. The final leg to Isla Fuerte is always a boat from Paso Nuevo, and crossings follow fixed schedules that depend on the sea, so we coordinate everything in advance.
Message us to check availability for December and we will build a full plan of dives and courses plus lodging around your dates.
