The weather becomes warm during the day and pleasantly cool at night, while rain showers are getting rare. You can expect average high temperatures between 18 C (65 F) and 27 C (81 F).
Higher temperatures and more sun help to warm up the sea, as the average sea temperature in April climbs to 16Â°C (61Â°F). This is still fairly cool water that is hard to stay in for extended periods of time.he end of April follows the same pattern, as there is even less rain, more sunny days, and a jump in the average daily temperature to 16Â°C (61Â°F). The lowest ever recorded temperature in Athens in April is 3Â°C (37Â°F), while the highest ever recorded temperature is 27Â°C (81Â°F).
