Key Dive Site Facts
Dive Site Overview
Exploring Merkanti Reef provides an accessible shore experience for divers discovering Malta's underwater world. New divers find this site appealing because of its manageable depth profile, with much exploration occurring within 10-12 metres (33-39 ft).
Qualified divers can extend their exploration, as the reef reaches depths beyond 20 metres (66 ft). Accessing the reef from shore means an entry point located approximately 300 metres away, in a small bay between the Westin Dragonara and Hilton Malta, near Merkanti Beach Club. A substantial surface swim or accurate underwater navigation is required to reach the reef system from shore.
Boat access offers a more direct approach to the dive area, about 150 metres from the nearest coast. Merkanti Reef operates as a less-frequented dive, which promises a quieter experience.
Its dual reef structures run parallel to the coastline, presenting interesting topographical features even in shallower sections. Such relative tranquility supports focused observation of marine life and unhurried movement through the reef.
Divers can benefit from longer bottom times within recreational depth limits due to a gradual slope.
Best Time to Dive
Planning a dive at Merkanti Reef is generally favorable during Malta's warmer, calmer months, reflecting the overall 'Good' dive scores from June through October. Air temperatures during this period typically range from 24.9°C (76.8°F) in June to 22.9°C (73.2°F) in October, peaking at 28.4°C (83.1°F) in July. Rain is minimal during summer, with July experiencing zero average rainfall and August only 0.18 mm. Wind speeds are also considerably lower, averaging around 18-20 km/h (11-12 mph), resulting in calmer wave heights, often below 1 meter. Conversely, winter months, from November to April, show 'Moderate' dive scores due to cooler air temperatures, higher rainfall, and increased wind and wave activity, potentially affecting shore access and visibility. Water temperatures for this specific site are not consistently reported in available data, but generally follow the seasonal air temperature trends of the region.

Dive Experience & Conditions
Navigating to Merkanti Reef from shore involves a medium access level, necessitating either a longer surface swim or proficient underwater navigation from the designated entry point. Once underwater, divers encounter the dual reef structures, which provide various features for exploration. The top sections of both reef parts nearly reach the surface, creating natural light interplay. Depths for recreational diving average around 10 metres (33 ft), making it comfortable for extended bottom times. Experienced divers can explore deeper areas, with maximum depths recorded at over 20 metres (66 ft). Conditions, particularly visibility and current, can vary. Surface conditions, including wave height and wind speed, are notably calmer during the summer and early autumn months, which can ease the surface swim component of a shore dive.
Dive Difficulty & Safety Guidelines
Diving Merkanti Reef requires awareness of its specific environmental and logistical considerations. Due to its offshore nature and shore entry requiring a substantial swim, carrying a Delayed Surface Marker Buoy (DSMB) is advisable. This allows you to signal your position to any potential boat traffic, which can occur in this coastal area. While Merkanti Reef is identified as a beginner-friendly site in terms of depth, understanding and managing your air consumption during the surface swim or underwater navigation phase is crucial. There are many small overhangs and crevices to explore, but divers should maintain proper buoyancy control to avoid damaging delicate marine structures. Always dive within your certification limits and consider the prevailing weather conditions before embarking on a shore dive.
