Key Dive Site Facts
Dive Site Overview
Exploring Tobago's dive landscape, including the Tyrrel's Bay vicinity, offers divers varied experiences across its Atlantic and Caribbean shores. A prominent wreck on the Caribbean side is the M.V.
Maverick, a former ferry resting upright on a sandy bottom at 30 m (100 ft). Purposely sunk in 1997, it rapidly evolved into an artificial reef; sponges and deepwater purple sea fans now thickly cover its superstructure and hull. Divers can navigate interior portions, carefully prepped for relatively safe penetration by removing hazardous obstructions before sinking.
Unlike many Tobago sites, the Maverick features mooring buoys, simplifying entry. On the Atlantic side, sites such as Flying Reef, about a mile offshore from Crown Point, demonstrate prevailing currents' powerful influence.
Its reef surface, around 15 m (50 ft), features raised areas and low points, supporting a vibrant ecosystem of sea fans, plumes, rods, and various coral heads and sponges. Moderate to strong currents transport nutrients fostering abundant soft coral growth.
Diving here often involves drift diving along the coastline. Tobago's dive experiences are often "predictably unpredictable," with one side calm while another features a steady flow, making adaptability key for planning.
Best Time to Dive
Optimal diving conditions around Tyrrel's Bay typically emerge from January through June. During these months, visibility is generally at its best. Based on climate data, air temperatures range from approximately 26.5°C (79.7°F) in January to 27.9°C (82.2°F) in May, making surface intervals comfortable. Water temperatures consistently hover around 26.6°C (80°F) throughout the year. From June to November, rainier conditions arrive, with average monthly rainfall varying significantly; for instance, it peaks around 4.7 mm (0.19 inches) in July before dropping to 1.7 mm (0.07 inches) in September. Increased precipitation, coupled with potential runoff from the Orinoco River, can substantially impact underwater visibility. Wind speeds are generally moderate year-round, ranging from 17.6 km/h (10.9 mph) to 25.2 km/h (15.7 mph), contributing to wave action, which averages between 0.85 m (2.8 ft) and 1.38 m (4.5 ft). Humpback whale sightings in Tobago's waters are common from late January into May, though rarely experienced by divers themselves.

Dive Experience & Conditions
Diving conditions around Tyrrel's Bay present a clear duality between Tobago's coasts. On the Atlantic side, expect drift diving; sites like Flying Reef often feature a steady, moderate current. Such a flow actively sculpts underwater topography and fosters extensive soft coral growth, providing shelter for diverse small schooling fish. Visibility in northern areas typically reaches around 24 m (80 ft), though specific days might see it drop to 15 m (50 ft). In contrast, Caribbean side conditions, as found at the M.V. Maverick wreck, are notably calmer, with currents generally absent. Unhurried exploration of the wreck is possible, resting at a maximum depth of 30 m. Most dives in Tobago begin with a backroll entry from a live boat; moorings are not consistently available, with the Maverick being a notable exception. Careful group management and thorough briefings are essential for safe operations. Divers navigating deeper sections, particularly wrecks, must remain vigilant regarding bottom time and no-decompression limits.
Dive Difficulty & Safety Guidelines
Prioritizing site-specific knowledge and dive planning is crucial when exploring waters near Tyrrel's Bay. Given Tobago's "predictably unpredictable" conditions, always consult with local dive operators about current reports and expected visibility before each dive. Many Atlantic-side sites involve drift diving due to persistent currents; ensure precise buoyancy control to avoid unintended reef contact. On wreck dives, particularly those with penetrable sections like the M.V. Maverick, exercise caution against stirring up silt, which quickly reduces visibility. Furthermore, divers exploring deeper sites, such as the Maverick wreck at around 30 m, must diligently monitor their depth and time. Almost all dives begin with a backroll entry from a live boat, as moorings are limited; comfortable boat diving skills are essential. Although hazardous obstructions were removed from wrecks like the Maverick prior to sinking, interior navigation still demands advanced training and careful execution. Always dive within your certification limits.

Verified equipment recommendations for this dive site are being reviewed and may be added as additional source checks are completed.
Recommended Dive Suit
Divers planning deeper dives may feel cooler than those staying in shallower areas.
Many divers find that 2-3mm shorty or light wetsuit offers a comfortable balance between warmth and mobility. Consider warmer surface protection (like a boat coat) due to brisk winds. Forecast trends indicate similar diving conditions over the next few days.
Current temperature readings suggest that the water at Tyrrel Bay is around 28°C (82°F). Surface air temperatures are resting at 27°C (81°F).

Marine Life at Tyrrel Bay
Varied habitats support marine life around Tyrrel's Bay, shaped by currents on the Atlantic side and calmer conditions on the Caribbean. Reefs boast extensive soft corals, alongside brightly colored tube and misshapen barrel sponges, especially where currents deliver rich nutrients. Expect to encounter French angelfish, white-spotted filefish, and various schooling fish like bar jacks, grunts, chubs, creole wrasses, and blue chromis. Nurse sharks are often seen on sandy bottoms, and large green moray eels frequent sites on Tobago's northeast end. Hawksbill turtles are present, as are porcupine puffers. Wrecks, like the M.V. Maverick, become artificial refuges attracting silversides and diverse reef fish.

Frequently Asked Questions
What are the typical water temperatures in Tyrrel Bay?
Water temperatures consistently hover around 26.6°C (80°F) throughout the year. Conditions are generally warm for diving.
How does visibility change throughout the year?
Visibility is generally best from January to June. From June to November, rainier conditions and runoff from the Orinoco River can reduce underwater clarity. Northern sites typically offer better visibility around 24 m (80 ft).
What can I expect regarding currents?
Currents in Tobago are "predictably unpredictable." Atlantic-side sites, where Tyrrel's Bay faces, often feature moderate to strong currents suitable for drift diving. Caribbean sites, like the M.V. Maverick wreck, are typically calmer with minimal current.
Is the M.V. Maverick wreck suitable for all divers?
Sitting at 30 m (100 ft), the M.V. Maverick wreck has penetrable interior sections. While hazardous obstructions were removed, interior navigation requires advanced training. Its depth necessitates careful monitoring of bottom time.
Are there many mooring buoys in Tobago?
Mooring buoys are not common across Tobago dive sites, with the M.V. Maverick being one of the few exceptions. Most dives will involve a backroll entry from a live boat, necessitating comfortable boat diving skills.
What type of marine life might I see?
