Dog Island is an uninhabited cay in the Caribbean Sea, sitting several miles northwest of mainland Anguilla and reached exclusively by boat. The area is a designated marine park, and its sites range from shallow beginner-friendly reefs and a deliberately sunk wreck to wall and drift dives where strong currents run along sheer drop-offs. Water temperatures are warm year-round, cooling slightly in winter and peaking in late summer. The seven sites here cover a broad spread of diving styles, and the remoteness of the location keeps visitor numbers low.
Monthly water temperature across Dog Island's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures sit in the mid-to-upper twenties Celsius through winter and spring, rising to around thirty degrees by September before easing back in December. Calmer seas and better visibility are generally found during the dry season from December to May, while exposed open-water conditions at the wall and drift sites mean trips remain weather-dependent throughout the year.
Water temperature around Dog Island ranges from about 27°C in January to 30°C in September, based on satellite sea-temperature data for its dive sites.
