Malta has a Mediterranean climate that offers warm sea temperatures from July to October. Summer lasts until the end of September, which is the best time to scuba dive in Malta; the temperature remains at 26°C (79°C) as the sea has heated all summer, and you can avoid the tourist peak season.
Thanks to its numerous shore dive sites located all around the island, scuba divers can find a sheltered spot every day, even in winter and the windy days of spring. Knowing what the water temperature will be at the time of your trip will help you determine if this is the best time to dive in Malta.
You will find below, month by month, the average water temperature in Malta. Note that the Maltese archipelago is small; you can expect the same water temperatures when diving in all of the Maltese Islands (Malta, Gozo, Comino).
