Yes!
I got this from weatherspark:
"The hottest month of the year in Göcek is
August, with an average high of
32°C and low of
20°C"
it clearly says "average".
and I got this from myweather2:
"In recent times the highest recorded temperature in August has been 43°C"
I assume that you are chartering the
boat and going with those people to spend a great time there?
I wouldn't just say that it is worth this extra
money, it is absolutely necessary.
