Gradations of Post-Summer Summertime.

Brought to you by the Church of England, and explicated by Webster's New International Dictionary, Second Edition (1939):

Indian summer. a A period of warm or mild weather late in autumn or in early winter, usually characterized by a clear or cloudless sky and by a hazy or smoky appearance of the atmosphere, esp. near the horizon. The name is of American origin, the reason for it being uncertain; it is now also used in England. In England, the period, when occurring in November, is also called St. Martin's summer (St. Martin's Day being Nov. 11), when occurring in October, St. Luke's summer or little summer of St. Luke (St. Luke's Day being Oct. 18), chiefly dialectically; when occurring in September, St. Austin's, or St. Augustine's, summer. Formerly Allhallow summer (All Saints' Day being Nov. 1) was also used in England. b A brief period during which past favorable conditions recur.

We will find ourselves at the start of a brilliant St. Luke's summer here in Maunder tomorrow, which will last at least several more days. I for one am going to be getting myself outside as much as possible!
