From Mar 21 to Mar 23, 2026, the price of 15°C crashed from 26.5c to 11.5c, and 14°C plummeted from 18c to 4.5c; simultaneously, 16°C surged from 27c to a peak of 48c (settling at 39.5c), and 17°C climbed steadily from 22c to 33c. The reason is that as the target date arrived, weather models formed a consensus around 'warm and sunny' conditions, dismantling the cooler thesis (14-15°C) and forcing capital into the 16-17°C bracket.
From Mar 19 to Mar 21, 2026, the price of 17°C surged from 10c to 29c, and 16°C rose from 16.5c to 33c, as mainstream sources like Google and Meteo.it locked forecasts into the 16-17°C range, establishing a new consensus.
