September 1st and autumn is here, but there is always a lively discussion as to what date is the true start of autumn. There are three definitions: meteorological, celestial and those derived from the changes in nature.
For consistency and comparison of weather records, the Met Office nominates three month cycles, each commencing on the first of the month.
Astronomers utilise celestial events such as equinoxes and solstices with autumn occurring this year on September 22nd.
Phenology, or the study of periodic plant and animal life cycle events, dictates that autumn is here when oaks and beech trees start to tint and the ripening of sloes and elderberries is evident etc.
Well, the sloes and elderberry are everywhere in the combe, so I stick with the first of September as the true start of autumn - my favourite season
