How many days will New Orleans be above 90°F?

Currently, prediction market odds offer a unique perspective compared to traditional analyst forecasts for weather events. While many analysts provide seasonal outlooks, this market focuses on a specific, short-term period – the week of September 14, 2026 – and aggregates the wisdom of the crowd. It’s common to see discrepancies between expert predictions and market prices, as the market incorporates a wider range of information and continuously updates based on new data. This dynamic pricing can reveal insights that static forecasts might miss, offering a different lens through which to view the likelihood of sustained high temperatures in New Orleans.

On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing ‘yes’ or ‘no’ outcomes, and the price fluctuates based on supply and demand. As more people buy ‘yes’ contracts (believing New Orleans will have consecutive 90°F+ days), the price of ‘yes’ increases, and the price of ‘no’ decreases. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. This mechanism allows the market to dynamically reflect the collective probability assessment of all participants. The closer we get to the resolution date, the more sensitive the prices become to new information and changing expectations.

This market resolves around Sep 22, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will depend on whether New Orleans officially records consecutive days with an average temperature exceeding 90°F during the week of September 14, 2026. Data will be sourced from established meteorological agencies and weather databases to ensure an accurate and impartial determination. The final outcome will reflect the actual recorded temperatures for that week, as reported by these trusted sources.

Several factors could significantly influence trading in this market. Long-range weather forecasts issued by the National Weather Service or other meteorological organizations will be closely watched. Any indications of a developing high-pressure system or unusually warm air mass over the Gulf Coast could drive up the price of ‘yes’ contracts. Conversely, forecasts predicting cooler temperatures or increased cloud cover could lower those prices. Unexpected events like hurricanes or tropical storms impacting the region could also introduce volatility, as they can disrupt typical weather patterns and influence temperatures in New Orleans.
