Using the ancient Turkish Storm Calendar we look ahead to see what the weather may be like this December and, more importantly, on Christmas Day too.
December in the northern hemisphere marks the time when the sun is at its weakest, when the days are the shortest and the nights cooler.
But what will the weather be like?
We consult the ancient and the more recent interpretation of a weather almanac to find out.
The Turkish Storm Calendar is 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 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, it is said, based on this almanac and their own weather observations.
They applied their own Turkish names to describe some of those significant weather events too.
So what does the calendar say about December?
4 December – A two day storm starts
6 December – A north wind will blow and no doubt temperatures will drop
7 December – Severe weather
9 December – More bad weather
19, 28 and 31 December – Storms on each day
So let's keep an eye on the calendar and see what happens!
Christmas Day Outlook
The 25th should be a sunny day.
How do we know?
Well, over the last 12 years we have been tracking the weather and, from our own observations, the 25th has always had some lovely sun.
