Best time to dive in Exumas

Optimal Diving Seasons

Peak Seasons

The best three months for diving in the Exumas are typically April, May, and June. During these months, the weather is consistently warm, and the water temperature is very comfortable, usually ranging between 78°F to 82°F (25°C to 28°C). These conditions create an ideal underwater environment for divers to explore the vibrant marine life and coral reefs that Exumas is known for. Additionally, these months often present excellent visibility underwater, making it easier to spot the diverse array of aquatic species.

Off-Peak Seasons

Pros and cons of diving during the off-peak seasons are considerable. The main off-peak months are from July to September. During this period, divers might deal with higher water temperatures, which can sometimes be less comfortable, ranging from 82°F to 86°F (28°C to 30°C). However, these months also come with the benefit of smaller crowds and often lower accommodation prices. On the downside, summer in the Exumas is also hurricane season, so the weather can be unpredictable, which might result in cancelled dives. It’s crucial for divers to keep an eye on weather forecasts and be prepared for potential changes.

Month-by-Month Guide

January to March: This period welcomes divers with cooler water temperatures, often around 75-77°F (24-25°C). The dry season means less rainfall and calmer seas, enhancing underwater visibility. Marine life, including reef sharks and groupers, is usually abundant during these months.

April to June: The spring to early summer months are characterized by warming water temperatures, rising up to 79-81°F (26-27°C). This time heralds the arrival of eagle rays and the peak of coral spawning, providing spectacular underwater displays. Rain begins to increase but does not significantly impact diving conditions.

July to September: These months are considered the hottest and most humid, with water temperatures peaking at 83-85°F (28-29°C). It’s hurricane season, so divers should be cautious and check weather conditions regularly. Marine life is still vibrant, with good opportunities to see larger pelagic species.

October to December: As the water begins to cool down to around 78-80°F (25-27°C), the weather becomes more temperate, and hurricane risks decrease. The sea remains clear, making it an excellent time for spotting nurse sharks, reef fish, and vibrant coral reefs. The holiday season also tends to bring more visitors, enhancing the social dive experience.

Diving Conditions

Water Temperature

The Exumas boast relatively warm waters throughout the year. In general, water temperatures range from 75°F (24°C) in the cooler months (December to February) to around 84°F (29°C) in the warmer months (June to September). These temperatures offer comfortable conditions for most divers, but wearing a 3mm to 5mm wetsuit is advisable, especially during the cooler periods.

Visibility

Visibility in the Exumas is generally excellent, often exceeding 100 feet (30 meters). However, it can vary seasonally. During the summer months (June to September), visibility tends to be at its best due to calmer seas and less wind. During the winter months (December to February), visibility can be slightly reduced due to increased wave action and occasional storms, but it typically remains very good.

Currents and Tides

The currents in the Exumas can be variable depending on the location and time of year. Some dive sites may experience stronger currents, particularly during the spring and fall when tidal exchanges are more significant. It’s important to dive with local guides who are familiar with the currents and tides to ensure safe diving experiences. Generally, diving during slack tide, when the tidal movement is minimal, is recommended for optimal conditions.

Recap

The Exumas offer unparalleled diving opportunities year-round, although the ideal times can vary depending on your specific interests. For those looking for optimal conditions, clearer waters, and calmer seas, the winter months from December to April are ideal. Warmer waters and vibrant marine life make the late spring to early summer months of May through July a great alternative for divers seeking unique encounters and comfortable conditions. However, those who prefer quieter dives can still enjoy the mesmerizing underwater world during the off-peak hurricane season from August to November, with the understanding of variable weather conditions.
