Although CMA forecasts a high of 20°C and AccuWeather predicts up to 23°C, Google Weather (likely de...

March 23 - March 24, 2026, the price of '19°C' surged from ~22c to 42c, while '20°C or higher' retreated from 52.5c to 39c. The driver was the T-24h forecast convergence: Google/TWC locked in a high of 19°C (67°F) with confirmed overcast/rainy conditions, undermining the previous sunny/warm (21°C+) thesis and forcing capital to pivot heavily towards the 19°C bucket.

Market pricing (favoring 19°C) diverges from CMA (20°C) and AccuWeather (23°C) official forecasts but aligns perfectly with Google/TWC (19°C). This indicates traders are pricing based on the resolution source's specific data bias (Wunderground often mirrors TWC) rather than the local meteorological authority (CMA).

Based on the latest forecasts from AccuWeather and The Weather Channel (Google Weather) as of March ...

March 21, 2026 - March 22, 2026, the price of '30°C or higher' crashed from 25.5c to 8c (rebounding slightly to 12.5c) because meteorological models revised earlier heatwave projections downward as the date approached, consolidating around a 27°C peak. March 21, 2026 - March 22, 2026, the price of '26°C' spiked from 17.5c to 34c (settling at 28c), and '27°C' rose from 17.5c to 29c, as forecast data clarified the target range to be 26-27°C, driving capital consolidation into these likely outcomes.

Although MetService officially forecasts a high of 20°C for Wellington on March 25, the note 'Easter...

March 22, 2026, the price of '21°C' crashed from 26.5c to 9.5c, while '18°C' and '19°C' surged from ~16c to around 29c. The driver was updated guidance from sources like AccuWeather favoring cooler temps (18-19°C) and market realization that the forecasted 'Easterlies' would cap heating, forcing a capital rotation from warmer options (20-21°C) to cooler ones (18-19°C). March 21, 2026, the price of '23°C or higher' crashed from 25.5c to 13.5c. The driver was the release of the updated MetService forecast predicting a high of only 20°C, effectively ruling out any heatwave scenario.

Significant divergence exists. While the official MetService forecast predicts a high of 20°C, the market prices 20°C (16c) significantly lower than 18°C (28.5c) and 19°C (28c). Traders appear to view the official forecast as optimistic, aligning closer with AccuWeather's 18°C prediction or the cooling effects of the expected Easterly winds.

March 23, 2026 (local Beijing time), the price of the 21°C option saw high volatility, spiking from 28c to 38c (+10c) before correcting back to 30.5c. This surge lacked meteorological support (mainstream forecasts remained at 20°C) and likely stemmed from intraday speculation or misinterpretation of early data. March 22 - March 23, 2026, the 20°C option initially dropped to 18c but rebounded to 24.5c as forecasts solidified, indicating a market correction from over-betting on warmer outcomes. March 20 - March 21, 2026, the 19°C option crashed from 40.5c to around 20c, marking a shift in market consensus from cooler temps toward the 20-21°C range.

Significant divergence exists. Polymarket traders are currently pricing 21°C as the favorite (~30.5% implied probability), whereas all major authoritative data sources, including Weather.com (IBM), AccuWeather, and the China Meteorological Administration, consistently forecast a high of 20°C. Market prices may be lagging behind the latest data or heavily hedging against potential heat island effects at the airport station.

Significant contradiction in the rules text. The first sentence explicitly states the market resolves based on the '3 day weekend of March 13 - 15' (past dates), while the title and the latter part of the rules specify the 'March 27 - March 29' weekend. While the market intent is clearly for the upcoming March 27 weekend given the settlement date (March 30), the 'March 13-15' typo creates a substantial risk for dispute resolution (e.g., if resolved on March 13 data, the winner would likely be 'Hoppers' or 'Reminders of Him' instead of the current favorite 'Project Hail Mary').
