From April 4 to April 5, 2026, the price of '16°C' rose from 16c to 30c, and '14°C' climbed from 15.5c to a peak of 28c. Meanwhile, '17°C' surged from 7c to 27c during April 4. This was driven by the release of updated short-term weather forecasts as the resolution date nears, locking the expected high temperature into the 14°C-16°C range, causing market capital to concentrate in these high-probability brackets and exit outlier options.

Predicting the exact highest temperature of a specific city on a specific day is a niche novelty topic in prediction markets. Unless extreme weather is expected, the general public typically does not think about this everyday phenomenon down to the exact degree.
