Diving atSecca di Washignton (Italy)
Approaching Secca di Washington, divers prepare for a boat entry onto a substantial rocky relief within the La Maddalena Archipelago. Your descent begins near the four visible buoys, positioned at roughly 4 m (13 ft) from the surface, serving as a clear starting point. This shoal, influenced by the Mistral winds, promises immediate engagement with its varied underwater terrain from the moment you enter the water.
As evening covers Secca di Washignton, the local air temperature is measured at 20.5°C. The current wave height at the surface is recorded at 1.2 m. These late-day readings characterize the surface conditions for the night.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
This site, also known as Secca Washington, is characterized by a prominent rocky relief crowned by huge granite blocks, which appear eroded from an aerial environment. The top of the shoal itself lies at about 6 m (20 ft) below the surface, but the structure rapidly expands downwards.
It's surrounded by a complex topography of boulders, landslides, tafoni, and depressions that extend to maximum depths of 25 m (82 ft). Several distinct itineraries are possible, branching out from the anchoring points of the four buoys. Exploring the site reveals a striking contrast: brightly lit areas are often covered by photophilic seaweed, while the more shaded sections host a dense collection of multicolored animal organisms.
This dynamic interplay between light and shadow defines much of the diving activity. This location, situated off Spargi island and near the Strait of Bonifacio, is subject to the influence of Mistral winds, which can impact conditions.

Optimal conditions expected
Current conditions near Secca di Washignton show 20° air, 21° sea temperature, 0.5 m waves, and 28 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
Optimizing for visibility and calmer seas, the best time to experience Secca di Washington typically spans from late spring through early autumn. During months like June to September, air temperatures generally range from 21.5-25°C (71-77°F), with significantly lower rainfall, often less than 1 mm, and reduced wave heights, averaging under 1 meter (3.3 ft). These conditions contribute to clearer water and a more stable diving experience. May and October also offer good to moderate diving scores, but with slightly higher chances of rain and increased wave activity. Visiting during periods of minimal wind, especially outside of peak Mistral influence, will usually ensure the clearest water and most comfortable boat journey to the site.

Dive Experience & Conditions
Exploring the depth profile at Secca di Washington involves navigating an impressive granite formation that begins near the surface and descends. Starting from the buoys at approximately 4 m (13 ft), you'll quickly encounter the shoal's top at 6 m (20 ft) before the relief drops off to deeper sections. These deeper areas are marked by large boulders and intricate rock formations, with the most profound depressions reaching 25 m (82 ft). Current strength varies, often influenced by the nearby Strait of Bonifacio and prevailing Mistral winds, requiring attentive dive planning. Water temperatures aren't consistently reported, but typically align with Mediterranean seasonal variations. This diverse underwater topography allows for a range of dive experiences, from shallower explorations of the illuminated seaweed-covered peaks to deeper excursions into the more sheltered, shaded crevices.
Dive Difficulty & Safety Guidelines
Diving at Secca di Washington requires awareness of potential currents, particularly due to its location near the Strait of Bonifacio and its exposure to Mistral winds. Planning dives to coincide with slack tides or periods of minimal wind can mitigate stronger flows, ensuring a safer experience. Always carry a surface marker buoy (SMB) for visibility on ascent, especially given the boat traffic in the area. Due to the varied depths, from the surface down to 25 m (82 ft), careful air management and monitoring of no-decompression limits are essential. Adherence to responsible diving practices, such as maintaining neutral buoyancy and avoiding contact with the delicate marine environment, is expected.

Recommended Dive Suit
Current diving conditions indicate water temperatures around 21°C (70°F) at Secca di Washignton. Surface air temperatures are resting at 20°C (69°F).
Forecasts suggest rising temperatures later this week. A warming trend is expected over the next few days.
In water temperatures like these, 5mm wetsuit typically offers sufficient warmth for most recreational dives. Consider warmer surface protection (like a boat coat) due to brisk winds. Surface intervals may feel cooler. Some divers naturally tolerate cooler water better than others. Stronger winds may also make surface intervals feel cooler than usual.

Marine Life at Secca di Washignton
The diverse underwater landscape of Secca di Washington provides a rich habitat, particularly in the contrasting illuminated and shaded areas. Divers frequently encounter significant fish, with large groupers, barracuda, and snappers commonly observed traversing the rocky relief. Brown meagers and common dentexes are often seen near the granite blocks, sometimes appearing confident and approachable. In the more sheltered, darker depressions, thousands of multicolored animal organisms thrive, adding vivid splashes of color to the rock faces. With some luck, larger pelagic species such as jacks and tuna may also pass through, especially near the deeper sections of the shoal.
