Ownership note: Website taken from its boat listing (Key Largo Diver II -> scubakeylargo.com)
Calm ~25 ft reef with the iconic bronze statue; good for beginners and snorkelers.
All-level spur-and-groove reef (~10-55 ft) with turtles, nurse sharks and snapper schools.
510-ft Navy ship wreck at ~65-130 ft with swim-throughs; advanced, often current.
May to September is usually calmest; December to May often has the clearest water (approximate).
Water temperature is about 72 to 86°F / 22 to 30°C (approximate).
As a general guideline, many divers wear a 3mm wetsuit in summer and a 3 to 5mm wetsuit in winter. Treat that as a guideline for typical conditions, not a forecast for one day.
Some of it is. Christ of the Abyss, at Key Largo Dry Rocks, is a calm reef about 25 ft deep and is described as good for beginners and snorkelers. Molasses Reef is an all-level spur-and-groove reef about 10 to 55 ft, with turtles, nurse sharks, and snapper schools. The USS Spiegel Grove is not a beginner dive. It is a 510-ft Navy ship at about 65 to 130 ft, with swim-throughs, and it often has current. Those notes come from the sources linked in the dive sites section.
A standard scuba dive calls for a certification. You do not need one for a Discover Scuba / try dive, which is a supervised introduction and not a certification card. BlueWater Divers, Ocean First Key Largo, Scuba-Fun Dive Center, and Horizon Divers list that offer. Key Largo Dive Center lists an Open Water course. Sail Fish Scuba had no courses detected on the pages checked for this list.
May to September is usually calmest. December to May often has the clearest water. Both ranges are approximate. Water temperature is about 72 to 86°F / 22 to 30°C (approximate). As a general guideline, a 3mm wetsuit is common in summer and a 3 to 5mm wetsuit is common in winter.
The USS Spiegel Grove is a 510-ft Navy ship wreck at about 65 to 130 ft, with swim-throughs. It is an advanced dive and often has current, so it is not a beginner site.
