April 6, 2026 - April 7, 2026, the price of the '18°C or below' option surged from 40.5c to 78c, because as the date approaches, weather forecasts confirm the highest temperature will be below 18°C. April 6, 2026 - April 7, 2026, prices for most options '19°C' and above experienced varying degrees of decline (e.g., '19°C' dropped from 22.5c to 12c, '20°C' from 18.5c to 6.75c), due to the decreased likelihood of higher temperatures in the forecasts.
