On May 2, 2026, the price of 22°C surged from 17c to 52c, 23°C spiked from 11.5c to 34c, and 24°C jumped from 3.9c to 23.85c. Simultaneously, prices for 20°C and 21°C crashed to near 0c. The reason is that real-time weather observations and updated daytime forecasts for the day showed temperatures rising significantly higher and faster than previously expected, leading the market to rapidly price out lower temperature outcomes.
