In German-speaking countries, a common term (also Martinssommer) for a period of good weather in the first third of November with stable high-pressure conditions, which enables a late grape harvest (November harvest). It is one of the meteorological singularities (colloquially "infinite") in the annual vegetation cycle, similar to the Ice Saints in May, the Sheep Cold in June and Indian Summer in September. In 2006, Germany had a somewhat delayed Martini summer, which began around 14 November and lasted until almost the end of the month. On 15 and 16 November, temperature warmth records for this period were broken in large parts of Germany.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
