A modern take on an ancient weather almanac provides another way to forecast the changing seasons along the Aegean and Mediterranean coast and countryside.

Wet and windy weather may come as a suprise to the visitor to the shores of south west Turkey expecting wall to wall sunshine.

The Turkish Storm Calendar – Ancient Forecasts Modern Take

But locals and some sailors know what weather to expect thanks to the Turkish Storm Calendar, a weather almanac that can trace its roots back two centuries.

The ancient Copts, the earliest Christians who still make up 12% of the population of Egypt, had their own version of the British Meteorologic Service (Met Office).

But rather than using multi-million Pound computers to forecast the weather their service was based on hundreds and hundreds of recorded weather observations.

All these had been consolidated into a weather almanac that included annual dates on which storms and significant weather could be expected.

The almanac became known in modern times as the Coptic weather calendar.

Mariners in Turkey created their own storm calendar with their own weather observations and applied Turkish names to those too.

Some people believe that the similarities between the Coptic Almanac and the Turkish table leave no doubt that they come from a common source and that there are strong indications that the source was of Egyptian, and probably of ancient origin and was based on scholarly research.

Whatever the heritage of the forecasts the Turkish Storm Calendar does, with an eerie accuracy, warn of significant weather in this area.

11 November – Unseasonally Hot

Wait and See

Now we need to wait and see what weather will arrive and if the information first set down by the Copts around 2000 years ago is still true today.
