The meteoblue office is located in the heart of Basel, putting us into the centre of the Fasnacht. The first picture shows 2 participants, the "Fasnächtler", in their traditional costumes. The second picture shows the view from our office, with the "Cliques (groups) and "Gugge" (brass bands) in their colourful costumes marching, and the "Waage" (floats) carrying artistic "lanterns" (poster lamps) through seas of confetti.
The Basel Fasnacht traditionally begins one week after carnival, on the sixth Monday before Easter at 4 o'clock in the morning and last for 72 hours. We have analysed the years 1980 to 2022 and checked how temperatures changed after Fasnacht. You can easily access the raw data for the analysis through our history+ interface, and the data for Basel is available as a free test - back to the year 1960.
The first chart shows the mean temperature around Fasnacht, 55 days before and 40 days after. The first graph shows the mean temperatures, whereas the red trend line confirms that the temperature increases after Fasnacht. Especially in 2022 (green line), the Fasnächtler have successfully driven away the winter with its cold mean temperatures. However, when analysing the minimum temperatures in the second graph, the increase is less visible, as the minimum temperatures increase only slowly after Fasnacht.
You can also individually analyse each year back to 1984 in our weather archive included in our point+ subscription.
The expulsion of winter at Fasnacht can thus be confirmed in terms of mean temperatures, even though it is less certain that the temperatures are actually reacting to our Fasnacht - they also increased in the past 3 years, when our Fasnacht was prohibiited because of the pandemic.
You can follow the temperature development in the next days with our 5 days and 14 days meteograms, to track if the Fasnächtler successfully drove away winter.
We wish all Fasnächtler a pleasant Fasnacht time!
