My experience from Sithonia: 

The most pleasant period for a vacation in Halkidiki (Sithonia) is in June and September. During these months, you will swimmingly enjoy the unique nature of this peninsula, the beaches will not be as crowded as in the peak summer season. Also, the weather is more pleasant, so you can stay on the beaches in the hottest part of the day (with sun protection). The swimming season in Sithonia usually starts in mid-May and lasts until October.

In addition to climatic features, other factors must be taken into account: 

✅ in July and August prices for everything (rent of apartments, cars, boats, groceries in the store) are much higher. Especially in August (the holiday period in Greece and many European countries). 

✅ In July and August, there will be much more tourists everywhere, including the Greeks themselves. Therefore, many beaches will be crowded.
