St. Luke's summer

1. A short period of warm weather around St Luke's Day (18 October); an Indian summer (also figuratively).
   • 1904, ‘Saki’, “Reginald's Rubaiyat”, in Reginald:

     to me there was something infinitely pathetic and appealing in the idea of the egg having a sort of St. Luke's summer of commercial usefulness.

   • 1934, Sir William Beech Thomas, The Yeoman's England:

     Almost every virtue of every season is contracted into the little span of St. Luke's summer, the very vintage of the year's juices.
