The Dodecanese Islands (also called Southern Sporades) are located in the southeastern part of the Aegean Sea, and have a Mediterranean climate
, with mild and rainy winters, and hot and sunny summers.
The main islands in the archipelago are: Agathonisi (or Gaidaro), Astypalea (or Stampalia), Kalymnos
, Kasos, Kastellorizo (or Megisti), Kos
, Leipsoi (or Lisso), Leros, Nisyros, Patmos
(the largest and most important), Symi, Tilos, and Halki (or Chalki).
Then there is a large number of smaller islands and islets, among which we can mention Pserimos (or Cappari), Farmakonisi, Telendos, Arkoi, Saria, Gyali, Levitha, Ro, Strongyli Megistis, Alimia, Syrna.
Lying in the eastern Aegean, the islands are warmer in summer than the Cyclades
, because they are affected on a less intense and continuous basis by the Meltemi
, the northerly wind that blows in summer in the central Aegean, except the most western islands such as Astypalaia, which have a climate similar to the Cyclades.
Even in winter the Dodecanese Islands tend to be milder compared with the Cyclades, in particular they are less susceptible to cold air outbreaks from the continent, as the winds from the northwest has to cover a wider sea area, so snowfalls in the Dodecanese Islands are very rare, and in practice snow never accumulates on the ground, at least in the plains. However, sometimes it can be a bit cold, so that lows can drop about 3/5 °C (37/41 °F), and highs to about 7/10 °C (45/50 °F), besides the wind can increase the feeling of cold.
Here for example, the average temperatures of Kalymnos.

in the Dodecanese Islands hovers normally between 650 and 750 millimetres (25 to 30 inches) per year, and is concentrated in the cold period, from October to March, when it can show up in the form of shower or thunderstorm, and can sometimes be abundant.
Because of the long summer drought, the landscape is typically semi-arid, especially in the flat islands and at low altitude (in some islands there are hilly and mountainous areas, which are greener).
This is for example the average rainfall in Rhodes.

The amount of sunshine
in the Dodecanese is great in summer, when clear skies are the norm. In winter, periods of bad weather, with cloudy skies, alternate with sunny periods.
The temperature of the sea
in summer remains somewhat lower in the central and northern part of the archipelago, as it does not exceed 23/24 °C (73/75 °F) in July and August, while it becomes higher in the southern islands such as Karpathos, Rhodes and Kastelorizo, where it can reach 25/26 °C (77/79 °F).
Here, for example, the temperature of the sea in Kos.

The best time
to go to the Dodecanese islands for a beach holiday is the summer, from June to mid-September. In early June, it can be a little cool in the evening: for safety you can bring a sweatshirt. Especially in the western islands, you can bring a light sweatshirt for windy evenings even in midsummer.
In May, not only the sea is still a bit cold, but even the air can be cool for sunbathing, at least on certain days.
To visit the ruins of ancient Greece or the cities, or for trips into the interior of the islands, you can choose spring, in April and May, since in summer it can be very hot. You can also choose autumn, at least in the first half of October, because then the rains increase.
