This is the fifth sunny dry day in a row in mid-Devon but it's not an Indian Summer, because according to the BBC Weather presenters "Indian summers don't occur in September", and I've heard that a couple of times today on the BBC.

They would be wrong. It's not dependent on month but rather, strictly speaking, a fine and warmer period after the first killing frost. However, it is a term borrowed from North America (New England, specifically); and perhaps we should return to the notions of Old Wives' summer, St. Luke's summer and St. Martin's summer - the latter two of which are date dependent (October and November respectively).

The AMS glossary summarizes Indian summer thus:

"A period, in mid- or late autumn, of abnormally warm weather, generally clear skies, sunny but hazy days, and cool nights.

In New England, at least one killing frost and preferably a substantial period of normally cool weather must precede this warm spell in order for it to be considered a true "Indian summer." It does not occur every year, and in some years there may be two or three Indian summers. The term is most often heard in the northeastern United States, but its usage extends throughout English- speaking countries. It dates back at least to 1778, but its origin is not certain; the most probable suggestions relate it to the way that the American Indians availed themselves of this extra opportunity to increase their winter stores.

The comparable period in Europe is termed the Old Wives' summer, and, poetically, may be referred to as halcyon days. In England, dependent upon dates of occurrence, such a period may be called St. Martin's summer, St. Luke's summer, and formerly All-hallown summer."


That's what I understand it by. We've had a couple of cold nights - but nothing approaching a frost. An 'Indian summer' is most likely in November down here...

You are guaranteed an Indian summer in autumn after a couple of hot curries,
for example a vindaloo.
Try it.
