Tropical storms have seasons, and so do monsoons and local winds — the meltemi in the Aegean, the bora in the Adriatic. Charter fleets move, insurance changes and marinas fill up around them.
Below: the season for each country as its weather service or government states it. Where sources disagree, both are given.
