April 28, 2026 - April 29, 2026: The price of the 26°C option dropped from 56.5c to 23.5c, while the 27°C option rebounded from 28c to 45.5c and the 28°C option rose from 12.5c to 26.5c. This was driven by the latest morning weather reports on April 29 indicating that daytime highs are expected to reach around 27°C, prompting the market to readjust its temperature expectations upward. April 27, 2026 - April 28, 2026: The price of the 26°C option surged from 23c to 49c, as the latest weather forecast from the Hong Kong Observatory explicitly narrowed the maximum expected temperature for the 29th down to around 26°C. April 27, 2026 - April 28, 2026: The price of the 27°C option rose from 22.5c to 39.5c, reflecting market anticipation that brief daytime sunshine before the cold front fully arrives could push temperatures slightly above the forecasted 26°C. April 27, 2026 - April 28, 2026: The price of the 28°C option plunged from 22.5c to 7.5c, because the forecast indicating a cold front and heavy rain significantly diminished the likelihood of experiencing temperatures as high as 28°C.
