Key Dive Site Facts
Dive Site Overview
Descending into Gozo's Blue Hole reveals a dramatic geological feature carved into the limestone, creating a circular sinkhole approximately 10 meters (33 ft) wide. This natural pool serves as a safe and calm entry and exit point for divers, especially when other sites might be exposed to stronger winds.
From the bottom of the sinkhole, at about 15 m (49 ft) deep, an impressive archway, often referred to as an underwater window, leads out into the open sea. This archway typically sits at around 9 meters. Beyond this arch, the dive extends to a maximum depth of 25 m (82 ft), where large boulders, remnants of the collapsed Azure Window now forming the Azure Reef, create an interesting landscape.
A large cave is also found opposite the archway, adding another element to the exploration. Divers frequently combine their Blue Hole experience with dives along the Azure Reef or Coral Gardens, offering a comprehensive tour of Dwejra's diverse underwater terrain.
Navigating the varied depths here provides opportunities to encounter different marine life patterns, transitioning from the sheltered hole to the more exposed reef environment.
Best Time to Dive
Optimal conditions for diving at the Blue Hole typically occur from June through September, aligning with Malta's peak summer season. During these months, the dive scores are consistently rated 'Good', with minimal rainfall, averaging less than 1.1 mm, and air temperatures reaching pleasant highs around 22.9-26.4°C (73-80°F). Wave heights also tend to be at their lowest, generally below 1 meter, and wind speeds are more moderate, ranging from 22-25 km/h. While water temperatures are not consistently reported in our climate data, they are generally warmest during this period. Conversely, the winter months, from December to February, present more challenging conditions; dive scores are 'Moderate', air temperatures drop to 15-17°C (59-63°F), and wave heights can exceed 1.7 meters, with higher wind speeds and increased rainfall, which may affect accessibility and overall visibility.

Dive Experience & Conditions
The Blue Hole presents a varied depth profile, beginning with a sheltered sinkhole that descends to approximately 15 meters. An advanced qualification is recommended to fully appreciate the site's features, particularly given the potential for deeper exploration outside the hole. Traversing the underwater archway, which is found at roughly 9 meters, opens into the wider sea. Here, divers can reach the site's maximum recreational depth. Navigating this area, divers will encounter significant rock formations and the scattered remains of the Azure Window. Water conditions inside the Blue Hole itself remain notably calm, providing excellent visibility for its interior walls. Outside, conditions can vary depending on swell and current, though the site is often dived in the afternoon when winds begin to increase, offering a more protected alternative to other exposed locations along the coast.
Dive Difficulty & Safety Guidelines
Navigating the approach to the Blue Hole requires consideration, as shore access involves a medium-difficulty walk of approximately 200 metres (650 ft) over rocky terrain while carrying equipment. Once at the site, the circular rock formation provides a notably sheltered pool, facilitating one of the safest water entries and exits in the area. An advanced diving qualification is recommended for this site due to its depth profile and the option to explore beyond the immediate confines of the hole into the open sea. Although the Blue Hole itself is protected, divers should remain aware of potential currents once outside the archway, especially when combining the dive with the Azure Reef. Standard safety protocols, including buddy diving and careful ascent planning, are essential here as with any open water dive.

Marine Life at Blue Hole
Upon entering the Blue Hole, divers often first notice the vibrant, colourful coral tubeworms and sponges adorning the walls of the sinkhole. These smaller organisms create a textured, living tapestry within the protected environment. Exiting through the archway and venturing towards the deeper areas, the larger boulders of the Azure Reef may reveal additional marine life. While not consistently reported in vast numbers, the area's crevices and the further reaches of the large cave sometimes shelter larger species, including the possibility of encountering Conger eels. Keep an eye out for various small fish species darting among the rocks and reef structures outside the main hole.

What is the maximum depth at the Blue Hole?
Within the sinkhole itself, the depth reaches approximately 15 meters. However, once divers pass through the underwater archway, the dive can extend to a maximum depth of 25 m (82 ft) in the open water beyond.
Is the Blue Hole suitable for beginner divers?
An advanced diving qualification is generally recommended for the Blue Hole. While the sheltered entry is safe, the site's depth profile and the potential for exploration in the open sea require a higher level of experience and skill.
How do you access the Blue Hole dive site?
Accessing the Blue Hole involves a walk of about 200 meters over rocky shore while carrying your dive gear. Despite the medium difficulty of the approach, the sheltered entry into the water from the sinkhole is considered one of the safest options in the area.
What kind of marine life can be seen there?
Divers can observe colourful coral tubeworms and various sponges lining the walls of the sinkhole. In the deeper sections beyond the archway and within the cave, there's a chance to spot other small marine life and occasionally Conger eels.
Can the Blue Hole dive be combined with other sites?
Yes, diving at the Blue Hole is often combined with exploring the nearby Azure Reef, which consists of the remains of the former Azure Window, or the Coral Gardens. Some divers also choose routes that connect with the Inland Sea, passing through the Blue Hole.
