Between April 27 and April 28, 2026, the Yes price for 13°C surged from 32c to 46.5c, while 14°C dropped from 37c to 28.5c. This was caused by the sharp reduction in uncertainty as actual early morning temperature data became available. Between April 26 and April 27, 2026, the price of 12°C spiked from 14c to 39c before plummeting back to 8c. Similarly, 11°C saw a rollercoaster movement from 3c to 23c and back to 4c. This was due to divergence in early weather forecasting models regarding the intensity of a cold front, which was subsequently corrected by short-term localized forecasts.
