Wherever you go in Turkey in June, the temperatures are likely to be hot, and average rainfall low. Southern and coastal regions tend to be hottest, with Bodrum and Antalya averaging 86°F (30°C). Istanbul in the northwest and inland Ankara and Cappadocia are a few degrees cooler but still pretty warm: expect average temperatures of between 75 and 78°F (24-26° C).
Crowds & Costs
Many people find the weather in June to be ideal for hitting up the beach but less ideal for walking around a city all day, and the crowds, costs, and availability of flights and accommodation reflect this. Big cities like Istanbul and Ankara won't be too busy with tourists and you may be able to find some accommodation deals.
That's less likely along the coast, as Turkey is a popular beach destination with travelers from all over Northern Europe. June may be less busy than later in the summer, though.
Where to Go
If you're into beaches and sailing, head straight to the Aegean or Mediterranean coasts. The port city of Fethiye, on the southwestern coast, is particularly appealing as from there you can hop on board a sailboat for an island-hopping adventure. Bodrum is also a good jumping-off point for some of Turkey's most popular beaches and the city itself has some interesting ancient sites as well as a Crusade-era castle.

What to Do
What you can do in Turkey in June will largely depend on how comfortable you are in the heat. If you just want to lounge on a beach, cooling off with a dip in the ocean periodically, then go for it. On the other hand, if you're comfortable walking around in the sun and want to check out a wider range of cultural, historic, and natural sites then you can do so in Istanbul, Pamukkale, Cappadocia, or Ephesus.
