Espíritu Santo is Vanuatu's largest island and the country's signature wreck-diving destination. The main dive cluster sits around Luganville, Segond Channel, Aore Island and Million Dollar Point on the island's southeast coast. The destination combines world-scale WWII wrecks including the SS President Coolidge (a 200m troopship), Million Dollar Point's underwater equipment museum, USS Tucker, coastal trader wrecks, protected channel reefs like Aore Wall and Cindy's Reef, and outer island reefs and walls at Bokissa, Tutuba and Araki with caves, swim-throughs and occasional pelagics.

The SS President Coolidge was a luxury liner converted to a troop carrier and sank in 1942 after hitting friendly mines while entering Segond Channel.The Coolidge is about 200m long and 25m wide, with divers often treating it as dozens of separate routes.Over 5,000 troops were aboard the Coolidge; sources state nearly all were saved after the captain ran her aground.The Lady statue is one of the wreck's signature deep route objectives — a porcelain figure in the ship's interior.Million Dollar Point exists because U.S. wartime equipment was bulldozed into the sea after WWII — jeeps, tractors, cranes and boats now form an artificial reef.Cargo Hold #2 of the Coolidge is known for flashlight fish on night dives, creating a bioluminescent spectacle among the wartime artifacts.

Month	Summary
Jan	Warmest month at 27-28°C with 12-25m visibility. Wet/cyclone season in full swing; schedule flexibility needed. Protected Coolidge wreck often still diveable despite weather.
Feb	Similar to January: 27-28°C, 12-25m visibility, high cyclone risk. Wet season conditions with humid air and frequent rain.
Mar	27-28°C with 12-25m visibility. Wet season easing late March but tropical lows still possible. Monitor weather forecasts closely.
Apr	26-28°C, 15-30m visibility. Shoulder month improving toward dry season. Good value transition month with improving conditions.
May	25-27°C, 18-35m visibility. Dry season begins with reliable reef and wreck diving. Excellent all-around conditions.
Jun	24-26°C, 20-35m visibility. Dry and settled weather. Peak visibility window begins; cooler water makes 5mm wetsuits useful for deep wreck dives.
Jul	24-26°C, 20-35m visibility. Dry and settled. Often the coolest water of the year; ideal for long deep Coolidge dives with proper thermal protection.
Aug	24-26°C, 20-35m visibility. Dry and settled. Often the coolest month; peak visibility with calm seas.
Sep	24-26°C, 20-35m visibility. Dry and settled. Strong all-around month — excellent conditions for wrecks and reefs alike.
Oct	25-27°C, 18-35m visibility. Shoulder month with warmer water returning. Usually still good seas as dry season winds down.
Nov	26-28°C, 15-30m visibility. Early wet season begins. Still workable diving but storm risk rises toward month end.
Dec	27-28°C, 12-25m visibility. Wet season with more rain and reduced offshore dive reliability. Shore-access wrecks like Coolidge remain options.
