Betting on the exact high temperature of a specific city on a single day is a niche novelty market. While not a serious topic of speculation in daily life, weather-related events have a dedicated audience on prediction platforms, so it is not exceedingly bizarre.

From April 20 to April 21, 2026, the price of 14°C surged from 23.5c to 41.5c, and 15°C surged from 14.5c to 36.5c, while 13°C plummeted from 31c to 16c. The reason is that as the date approaches, weather forecasting models have slightly revised the expected temperature upwards, moving from around 13°C to the 14°C-15°C range.

From April 20, 2026, 11:38 to April 21, 2026, 12:33, the price of the 41°C option surged from 30c to 49c, as forecast models gradually stabilized around 41°C, leading to more consistent market expectations. There have been no other significant price movements exceeding 10 cents for any option in the past 3 days. Market expectations remain relatively stable, concentrated on 41°C and 42°C.

Predicting the daily high temperature in a specific city is a niche but established category in prediction markets (akin to weather derivatives). While the general public doesn't typically think about Wellington's exact temperature, it is a standard topic for weather prediction enthusiasts.

From April 20 to April 21, 2026, the price of 12°C surged from 24.5c to 67.5c as approaching weather models became more confident that the high temperature would fall in this range. From April 20 to April 21, 2026, the price of 14°C plummeted from 15.5c to 2.65c because meteorological data indicated a very low probability of reaching 14°C.

Predicting the daily high temperature of a specific city is a relatively niche prediction market topic. While weather forecasting has an audience, it lacks the widespread public discussion of political elections or financial markets, generally attracting only weather enthusiasts or specialized weather traders.

April 20, 2026 - April 21, 2026, the price of the 16°C option surged from 26.5c to 43.5c, and the 15°C option spiked from 11c to a peak of 34.5c (currently around 29c-30.5c). This was driven by the nearing resolution date and updated meteorological models narrowing the expected high temperature confidence interval to 15°C-16°C, concentrating capital in these options. April 20, 2026 - April 21, 2026, the price of the 14°C option plummeted from a high of 23.5c to 4.5c, as updated forecasts indicated a slight warming trend, significantly reducing the probability of a 14°C high.

While weather forecasting is a normal part of life, demanding the exact high temperature of a specific city on a specific day to fall within a narrow range is a relatively niche and highly specific prediction market topic.

Divergence exists. The prediction market currently favors 30°C and 31°C as the most likely outcomes (with implied probabilities of 27% and 25%, respectively). However, mainstream meteorological forecasts (e.g., Wunderground, AccuWeather) indicate a high temperature between 28°C and 29°C for April 22. The market is pricing in significantly higher temperatures than weather experts predict, likely due to traders overreacting to recent subjective heat wave perceptions.
