I appreciate a lot "Poseidon system" as meteo forecast
for Aegean sea. The link is :
You have a lot of good shelters along the way to The Dardanelles.
I had southerlies in april 2 years ago, a strong Sirocco for 3 days and high temperature (35° C) in Kusadasi. The week after it was 18° and the usual moderate northerlies of this season.
The most important to know is the fact you can have very strong gusts
between the islands ans the coast, you can have 2 Beaufort
more in 5 minutes. So you have to be ready (for example : Cos/Turkey, Samos/ Turkey
, Chios/Turkey, etc...).
