The climate of Ithaca, a Greek island of the Ionian Sea, is Mediterranean, with mild, rainy winters and hot, sunny summers. At sea level, the daily average temperature ranges from 11.5 °C (52.5 °F) in January to 25 °C (77 °F) in August.
Here are the average temperatures (recorded in Argostoli, on the nearby island of Kefalonia).

The rains amount to about 700 millimeters (27.5 inches) per year, and are concentrated in the period from October to April, while in summer it rains very rarely.
Here is the average precipitation.

In the interior, there are hills, culminating in Mount Nirito, 800 meters (2,600 feet) high.



Winter, from December to mid-March, is mild but rainy, especially in December and January, when 100/110 millimeters (40/43 inches) of rain fall per month. However, there is a moderate amount of sunny days. Sometimes a cold wind from the north can blow, and the minimum temperature in the plains can drop to 0 °C (32 °F).

The spring, from mid-March to May, is mild; rainfall becomes gradually rarer over the weeks, and fine weather becomes more and more frequent. May is a good month, before the summer heat.

Summer, from June to mid-September, is hot and sunny: the maximum temperature often exceeds 30 °C (86 °F) and can even reach 35 °C (95 °F), especially in July and August; at worst it can reach 40 °C (104 °F). Luckily, sea breezes blow, providing relief, at least when the heat is not excessive, and in any case, you can cool yourself down in the sea.

Autumn, from mid-September to November, is mild (initially even quite warm) and rainy. In October, there may still be many sunny days.



The amount of sunshine in Ithaca is great in late spring and summer, when clear skies prevail, while from November to mid-March, sunny days alternate with periods of bad weather.

The temperature of the sea in Ithaca is high enough for swimming from July to September, while in June it is still a bit cool, around 22 °C (72 °F), but basically acceptable.
Here are the average sea temperatures.

Best Time

The best time to travel to Ithaca for a beach holiday runs from June to mid-September.
If you want to go on excursions around the island, the month of May or the first half of October are preferable in order to avoid the heat that sometimes occurs in summer.
