Predicting the exact highest temperature of a specific city on a given day is a relatively niche topic. While weather-related markets are common on prediction platforms, the general public rarely thinks about a city's exact daily high unless there is an extreme weather event.

From 00:48 to 06:13 on April 14, 2026, the price of the 19°C option surged from 22.5c to 98c, while the 20°C option spiked to 51c at 04:03 before plummeting to 1.5c. This occurred because real-time temperature data on the resolution day showed the high peaking at 19°C, failing to reach 20°C. Between 00:58 and 13:53 on April 13, 2026, the price of the 19°C option plunged from 37c to 13c, as the latest weather forecasts further confirmed cloudy and rainy conditions, significantly lowering the expected high temperatures. From 11:58 on April 12 to 12:48 on April 13, 2026, the price of the 17°C option surged from 8.5c to 37c, and the 18°C option jumped from 17.5c to 38c. This was caused by updated weather models anticipating a higher probability of precipitation, effectively locking the maximum temperature forecast into the 17°C to 18°C range. From 05:28 to 06:33 on April 12, 2026, the price of the 16°C option plunged from 26.5c to 14.5c. This was due to updated weather forecast models showing weaker cold air impact, significantly reducing the probability of the maximum temperature staying below 17°C. From 05:28 to 06:33 on April 12, 2026, the price of the 20°C option fell from 26.5c to 21.5c, reflecting a lower likelihood of temperatures reaching 20°C due to expected cloudy and rainy conditions.
