June is a great time of year to get that beautiful, guaranteed sunshine-all-day Mediterranean weather, without the stronger winds and bigger crowds of midsummer. It'll be around 80-85F - lovely and warm during the day, and mostly only need t-shirts and shorts at night too.
Although this isn't yet into "meltemi" season, the summer breezes will have picked up well by now, and it'll be great sailing weather.
There are two options for these dates: a 2wk all-Greece trip, a 2wk "combo" (Greece & Turkey) trip - just one week of either of these is possible too, of course!
