Best Time to Dive
While Greece generally offers favorable diving conditions through much of the year, the Old Quarry benefits from strategic seasonal planning for optimal comfort. Between March and November, the air temperatures are most inviting, ranging from 13°C (55°F) in early spring to a peak of 30°C (86°F) in July. During these months, the incidence of rain remains minimal, often less than 1 mm, creating clear days ideal for surface intervals. Conversely, the winter months, particularly December through February, see air temperatures drop to 11-12°C (51.8-53.6°F) and a noticeable increase in rainfall. Opting for the warmer, drier periods ensures more pleasant conditions both above and below the surface, enhancing the overall dive experience considerably.
