Diving atMartin Reef (United States)
Off the coast of Martin County, marine life thrives across a network of natural and artificial reef structures. This area, part of Florida's 'Treasure Coast,' benefits from a long-standing Artificial Reef Program, initiated in the 1970s by a group known as the 'Reeftirees.' These efforts have cultivated self-sustaining marine habitats, attracting a rich aquatic bounty for divers to observe.
During this afternoon at Martin Reef, the recorded air temperature stands at 27°C. The water surface currently features wave heights of 0.6 m. These conditions reflect the midday climate for this dive site.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Exploring Martin Reef means encountering a dynamic underwater landscape shaped by both natural formations and a purposeful artificial reef program. The initiative began decades ago, with efforts to create and enhance marine habitats using diverse materials.
Deployments have included steel vessels, such as the Hailey Glasrud Reef in the Sirotkin area, alongside numerous concrete rubble reefs found in sites like Donaldson. Nearshore reefs, established in 2000, utilize concrete debris from the former Evans Crary Bridge, creating complex environments between Stuart and Jensen Public Beaches.
These sites are regularly monitored for marine activity and structural integrity by research dive teams. Unlike some areas, Martin County waters typically do not feature mooring balls; instead, divers should anticipate and plan for drift diving, guided by the prevailing north current. Recreational depths across these varied structures allow for extended exploration.

Optimal conditions expected
Current conditions near Martin Reef show 27° air, 29° sea temperature, 0.3 m waves, and 15 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
Diving conditions at Martin Reef vary seasonally, generally presenting excellent opportunities for much of the year, though optimal periods stand out. The summer months, specifically May through August, consistently show high dive scores, marked by lower average wave heights, often below 0.8 meters (2.6 ft). During this time, air temperatures are warm, peaking around 28°C (82°F) in August, with moderate rainfall. In contrast, the fall, particularly October, sees an increase in wave heights, averaging over 1.6 meters (5.2 ft), and higher wind speeds, which can lead to more challenging conditions and a 'Moderate' dive score. Despite cooler air temperatures ranging from 18.5°C (65°F) to 23°C (73°F), winter and spring months from December to March still maintain 'Good' dive scores, benefiting from reduced rainfall compared to peak summer months.

Dive Experience & Conditions
A prevailing north current defines the diving experience at Martin Reef, making drift diving the standard approach for exploring these sites. Without mooring balls in Martin County waters, divers must be prepared to manage continuous movement throughout their dive. While specific water temperature data isn't consistently reported, surface air temperatures ranging from 18.5°C (65°F) in winter to 28°C (82°F) in summer suggest generally warm to mild conditions underwater. Reefs here present varying depths, from inner ledges just past no-motor buoys to deeper offshore sites. Shore divers must remain acutely aware of boat traffic, as vessels may approach shallower sections, necessitating constant vigilance and adherence to dive flag protocols.
Dive Difficulty & Safety Guidelines
Successfully navigating Martin Reef requires diligent attention to dive planning and safety protocols, particularly due to the prevalence of drift diving. Given the absence of mooring balls in Martin County, divers must coordinate boat pick-ups effectively and consistently deploy a surface marker buoy. Always maintain awareness of boat traffic; even in shallower areas, boats may come surprisingly close to inner ledges. Divers should understand that the local reef numbering can be confusing, with shore divers' 'third reef' often corresponding to what boaters consider the 'first reef.' Prioritize carrying appropriate navigation tools, such as the Navionics app, which often has wreck and reef locations pre-programmed, to enhance site awareness.
