April 17, 2026 - April 18, 2026, the price of the 20°C option surged from 2c to 22c, and the 21°C option rose from 13c to 28c, while 22°C and 23°C experienced high volatility and downward trends. This was driven by updated weather forecasts lowering the expected high to around 70°F (21°C).

Predicting the daily highest temperature of a specific city is a typical weather derivative in prediction markets. However, it lacks broad public attention and represents a relatively niche, data-driven regular market.

April 18, 2026 06:23 - April 18, 2026 11:48, the price of '31°C or higher' surged from 2.45c to 24.85c, and '30°C' spiked from 16c to a high of 34.5c. This was likely driven by new short-term meteorological data or heatwave warnings, causing investors to drastically raise their expectations for extreme high temperatures tomorrow. April 18, 2026 06:23 - April 18, 2026 11:48, the price of '28°C' plummeted from 31c to 14.5c, and '27°C' crashed from 26.5c to 6.5c. This is because, as expectations for a heatwave solidified, the previously favored lower temperature brackets lost their appeal.

There is a notable divergence. Mainstream weather forecast platforms (such as AccuWeather) predict the high temperature for Chongqing Jiangbei Airport on April 19 to be around 80°F (approx. 27°C) to 84°F (approx. 29°C). However, the prediction market experienced violent shifts just hours before maturity, assigning massive probabilities to 30°C and 31°C+. This divergence suggests that market participants might have access to more immediate heat warnings than public forecasts, or they are pricing in specific microclimate characteristics or historical upward biases at the ZUCK weather station.

While the general public rarely places precise bets on the specific high temperature of a city on a given day, this is a relatively standard short-term contract in prediction markets and weather derivatives, making its novelty level moderate.

April 17, 2026 - April 18, 2026, the price of 28°C surged from 24.5c to 45.5c, as weather forecast models became more certain that the high will hit 28°C as the date approaches. April 17, 2026 - April 18, 2026, the price of 30°C plummeted from 17c to 4.5c, due to downward revisions in temperature forecasts, significantly lowering the probability of reaching 30°C.

Predicting the exact daily high temperature of a specific city is a relatively niche prediction market. While weather forecasting has a dedicated user base on such platforms, the general public does not typically focus on such granular daily details.

Wunderground's official 10-day forecast projects a high of 26°C (78°F) for Taipei on April 19. However, the prediction market is currently pricing 28°C and 29°C as the most likely outcomes (at 25.5c and 24.5c, respectively). The market expectation is significantly warmer than the mainstream weather forecast, indicating a clear divergence.

Betting on the exact daily high temperature for a specific city (Warsaw) is a standard weather-related topic within prediction markets, yet it remains a highly specific and somewhat niche question that the general public rarely thinks about.

April 17, 2026 - April 18, 2026, the price of the 18°C option surged from 25.5c to 50.5c, as the resolution date approaches and weather forecasts become more certain, heavily concentrating market expectations on this range. April 17, 2026 - April 18, 2026, the price of the 19°C option dropped from 26.5c to 15c and then rebounded to 22c, reflecting market fluctuations driven by minor adjustments in weather forecasts.
