Ioannian VS Agean
What do the data found on the internet say?
Based on measurements taken over the past fifty years in the open sea, average values were taken and the following table was created.
|Temperature by regions
These data do not mean that in some years or decades, for example, Tasos was warmer than Halkidiki or Krf than Lefkada, but when average values are taken over the entire year (not just during the summer months) and the last 50 years, the data from the table are obtained.
Also, underwater sources were not taken into account, which make certain beaches or several beaches much colder than the average temperature that applies to the entire region or island.
An example of this are some beaches in the vicinity of Sivota, which have a lot of underwater sources, making them colder than the average temperature mentioned in the table.
I believe it is important to emphasize that sea temperature varies from beach to beach, as it depends on the depth of the sea and the length of shallow areas, the season, the amount of rainfall in a particular year, and the time of the year or summer season.
We also believe that both the Aegean and Ionian seas are warm enough to enjoy from June to September, and the temperature difference cannot exceed 2 degrees in favor of one or the other. Ultimately, even if the sea is sometimes slightly colder, it is not bad. There is nothing better than refreshing oneself when it’s extremely hot.
