The best Months to dive in Sihanoukville
Sihanoukville offers year-round diving opportunities with warm tropical waters. Water temperatures typically range from 28°C to 30°C/82°F to 86°F throughout the year, providing comfortable conditions for divers. Visibility generally varies from 5 to 15 meters/16 to 49 feet, with the best clarity often found during the dry season.
The dry season, from November to April, brings calmer seas and better visibility, ideal for diving. Conversely, the wet season, spanning May to October, introduces stronger winds and currents, which can reduce visibility and increase surface chop. Despite these changes, diving remains possible year-round, though the wet season is considered less favorable due to rougher conditions.

Seasonal highlights include the occasional sightings of blacktip reef sharks, especially during the cooler months.
