Though today’s weather is forecast to be cooler, we’ve had some nice warm temperatures around here lately. I always thought that any stretch of summery days this time of year could be called Indian Summer. But according to the Old Farmer’s Almanac (“Useful, with a pleasant degree of humor”), a true Indian Summer must meet several criteria:
Temperatures are warm, but the atmosphere must also be “hazy or smoky,” with high barometric pressure, no wind, and cool nights, all of it caused by a “stagnant anticyclone high pressure weather system;”
The warm days must be preceded by a cold snap or hard frost; and
Indian Summer must occur between St. Martin’s Day (November 11) and November 20. As the old saying goes, “If All Saints (November 1) brings out winter, St. Martin’s brings out Indian Summer.”
What, you’ve never heard that one? Me, neither. And how about St. Swithin’s Day—which I always thought was made up because I heard it on The Simpsons. (Bart: “Kippers for breakfast Aunt Helga? Is it St. Swithin’s Day already?”) Apparently, it’s a real saint’s day that occurs on July 15. I better mark my calendar for next year.
Anyway, even though we’ve had the hard frost and the unseasonably warm temps, it’s too early to call this Indian Summer. Makes me wonder how something that happens in November can be a ‘summer’ anything. But there you have it. Those Old Farmers wouldn’t lie.
