Greek Weather An outstanding feature of the Greek climate is its ample sunshine. It is no exaggeration to state that the sun shines over 300 days per year.

Average daytime temperatures in Athens in April are between 20-25 degrees C. (68-77 F.), rising in May by about 2 degrees.
In June, July and August it warms up to between 25-35 degrees C. (77-95 F.) and in September / October this drops to 22-27 degrees C. (70-79 degrees F.). 

The islands are 2-5 degrees C. below these temperatures and generally have much more pleasant weather.  Water temperature in the Sea during June, July, August and September average about 24 degrees C. (72 degrees F.)
