The Theresian Indian Summer is coming

Cooler weather with showers will remain in the Czech Republic until Tuesday. From Wednesday, the late, so-called Theresian Indian summer will arrive, sunny temperatures above 20 degrees Celsius.

It should cool down again at the end of the week. The drop in temperatures will then slowly continue until the end of October. This is according to information from the Czech Hydrometeorological Institute (ČHMÚ).

In the middle of the week, warm air from the south will enter the Czech Republic. “It will bring to the Czech Republic, plagued by cold weather for over half a month, at least for a few days, the late summer, known as the Theresian summer in this period,” said the CHMI.

Thus, sunny conditions are expected from at least Wednesday to the weekend, with local fog mainly lasting only in the morning and temperatures above 20 degrees Celsius.

The forecast calls for up to 21 degrees Celsius on Wednesday and 22 degrees for the rest of the week. Primarily cloudy weather with showers or rain may return by the end of the weekend. High daytime temperatures are expected to be in the range of 12 to 17 degrees Celsius.

The long-term outlook for October is for average temperatures. From next week onwards, the thermometer’s mercury will no longer exceed 18 degrees and continue to fall. Towards the end of the month, it will be the coldest, three to 11 degrees Celsius.

The Theresian Summer, or the Summer of St. Theresa, is one of the Indian summer seasons. The days are counted from the middle of the first decade of October to the days at the turn of the second and third decade of October, the CHM explained on Twitter. I

n the Indian summer, from the middle of the first decade of September, the Theresian summer is preceded by the Marian, Ludmilla-Matushka, and St. Wenceslas summers.

These are old folk names, as they are for the following Shimonian coolness in the last decade of October. After them, more sunny days may return in the so-called Little Indian Summer or the Summer of All Saints in early November, the Czech Hydrometeorological Office said earlier on its website, referring to the publication The Great Preanosticon by Zdeněk Vaska.
