Wind and Weather Conditions – Intermediate to Advanced
In the summer the prevailing wind is the Meltemi blowing from the NW-W. It starts fitfully in June, blows strongly in July through to September and again fitfully in October. In the summer months it regularly blows Force 4-6 and may on occasion reach Force 7. It does not blow every day, but may blow without break for 5-10 days. When the Meltemi is blowing at full strength in July and August the gusts off the lee side of an island can be considerably stronger than the wind strength in the open sea. Gusts are particularly strong off Patmos, Kalymnos, Kos, Nissyros, Tilos, Karpathos and Astypalea. In the comparatively open stretch of sea between Astypalea and Karpathos a large and distributed sea is set up when the Meltemi blows for days on end. Although it is possible to go N when the Meltemi is blowing, it makes better sense to plan to be heading S in July and August. The typical short seas it sets up make sailing or motoring to windward arduous and tiring. In spring the Meltemi blows mainly SE and is not very strong. During the winter it usually blows SE and sometimes N or S. Temperatures in the summer can reach 35 degrees Celsius.
The island of Rhodes has dominated this part of the Aegean since ancient times. The islands were under turkish occupation until 1912. Despite the long period of their occupation they remained Greek. After the Venetian war the islands were under Italian occupation until the second world war. In 1947 they became Greek again.
