Optimal Diving Seasons

Peak Seasons

Month-by-Month Guide

Turneffe Atoll offers year-round diving opportunities, but the conditions can vary significantly from month to month. Here’s a detailed guide to what you can expect throughout the year:

January to March

In the beginning of the year, Turneffe Atoll is blessed with cooler, dry weather. Water temperatures hover around 78-80°F (25-27°C), making it comfortable for both short and long dives. Visibility is often excellent, ranging from 80 to 100 feet (24 to 30 meters). Marine life is vibrant during this period, with more frequent sightings of eagle rays, groupers, and occasional reef sharks.

April to June

As spring transitions to early summer, water temperatures begin to rise slightly, reaching about 82-84°F (28-29°C). This period sees a slight increase in plankton, which can reduce visibility to some extent (around 60-80 feet or 18-24 meters), but also attracts larger filter feeders like whale sharks. This is also a prime time for spotting nurse sharks and a variety of smaller reef fish.

July to September

During these months, the weather tends to be warmer and more humid, with water temperatures peaking at 85-87°F (29-31°C). The increased temperatures can bring about thunderstorms, and the visibility can fluctuate between 50 to 70 feet (15 to 21 meters). Despite the variable conditions, this is a great time to see coral spawning events and enjoy night dives with bioluminescent organisms.

October to December

Late in the year, Turneffe Atoll transitions back to cooler and drier weather. Water temperatures drop slightly to about 80-82°F (27-28°C). Visibility improves again, reaching up to 100 feet (30 meters). This is an excellent time for divers interested in seeing larger pelagic species such as barracudas and jacks, as well as the occasional encounter with dolphins.

Diving Conditions

Water Temperature

Such comfortable temperatures make diving enjoyable year-round, though divers may prefer different wetsuit thicknesses depending on their cold tolerance and season.

Visibility

Visibility in Turneffe Atoll is generally excellent, ranging from 50 to 100 feet (15-30 meters).
