Fair Value Reasoning:

Integrating multiple weather sources (Meteoprog forecasts 23°C, Weather25 forecasts ~25.5°C with rain), a cooling trend with precipitation is expected for Buenos Aires on March 21. The anticipated rainfall (0.37 in) will likely suppress maximum temperatures, placing the most probable outcome in the 23-26°C range. The market currently significantly overprices the probability of temperatures 27°C and above (aggregating ~49%), and the pricing of 30°C (8.5c) being higher than 29°C (6c) indicates irrational pricing.

Movers

March 17, 2026 11:20 - 14:35, the price of '24°C or below' crashed from 25.5c to 10c and then quickly rebounded to 25.5c, likely due to a liquidity gap or a 'fat finger' trade causing a flash crash that was subsequently arbitraged back. March 17, 2026 14:35 - March 18, 2026 10:05, the price of '24°C or below' rose from 25.5c to 31.5c, as updated weather forecasts confirmed rain and cooling trends for the 21st, leading the market to price the lower temperature outcome more accurately.

Divergence

There is a significant divergence between the market and mainstream forecasts. The market pricing implies a near 50% probability of temperatures exceeding 26°C, whereas mainstream meteorological agencies (e.g., Meteoprog, Weather25) consistently forecast rain and maximum temperatures between 23-25.5°C. The market is aggressively overpricing the tail risk of a 'sunny and hot' outcome.
