This event tracks whether New Orleans will experience consecutive days of high temperatures during a specific week. It focuses on the number of days in a row where the average temperature exceeds a set threshold, reflecting potential heatwave conditions.
The event evaluates multiple thresholds for consecutive days of elevated average temperatures in New Orleans from September 21 to September 27, 2026. Each market resolves to Yes if the daily average temperature at KMSY airport remains strictly above 90°F for a specified minimum number of consecutive days—ranging from two to six days. The average temperature for each day is calculated as the mean of hourly temperatures reported by The Weather Company from midnight to midnight local time, rounded to the nearest whole degree. Only days within the specified week contribute to streaks, and a day with exactly 90°F or fewer than 18 hourly reports breaks any streak. All data used for resolution is taken from the published values at expiration, with later revisions disregarded.
Currently, prediction market odds offer a distinct perspective compared to traditional analyst forecasts for weather events. While analysts may provide seasonal outlooks and probabilities, this market aggregates the wisdom of the crowd, reflecting real-time adjustments based on evolving information and diverse viewpoints. It's important to note that analysts' predictions are often based on models and historical data, while this market incorporates subjective factors and potential unforeseen circumstances that could influence the actual number of consecutive hot days. Discrepancies can arise due to differing methodologies and the inherent uncertainty surrounding long-range weather predictions.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing potential outcomes. The price of a contract indicates the probability of that outcome occurring, with higher prices signifying greater confidence. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders set the odds based on their own research, analysis, and beliefs, and the market price dynamically adjusts as new information becomes available. The current price reflects the collective judgment of all participants, offering a unique and forward-looking assessment of the likelihood of a prolonged heat wave in New Orleans.
This market resolves around Sep 29, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will be based on the average daily temperature recorded in New Orleans during the week of September 21, 2026. The number of consecutive days exceeding 90°F will be tallied, and the market will settle according to whether the specified threshold is met. The data will be sourced from established meteorological organizations to ensure accuracy and reliability.
Several factors could significantly influence trading activity in this market before Sep 29, 2026. Long-range weather forecasts released by organizations like the National Oceanic and Atmospheric Administration (NOAA) will be closely watched. Any indications of a developing El Niño or La Niña pattern, which can impact regional temperatures, could trigger price movements. Additionally, unexpected shifts in global climate patterns or the release of studies predicting increased frequency of extreme weather events could also affect trader sentiment. Finally, any major news regarding climate change mitigation efforts or energy policies could indirectly influence perceptions of future temperature trends.
