The minimum temperature in San Antonio on June 11, 2026, will be recorded by the National Weather Service, with the outcome depending on which temperature range is observed.
Resolution is determined by the minimum temperature recorded at San Antonio on June 11, 2026, as reported in the National Weather Service's Climatological Report (Daily). The market divides the temperature range into five distinct bands: 70°F or below, 71-72°F, 73-74°F, 75-76°F, 77-78°F, and 79°F or above. Each temperature range corresponds to a specific market outcome. Official data must be obtained from the NWS Climatological Report accessed via the specified URL, selecting San Antonio with Daily Climate Report. While preliminary data from other sources like AccuWeather or Google Weather may provide guidance, only the official NWS Climatological Report (Daily) determines final resolution. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect interpretation of borderline values.
On Kalshi, the lowest temperature in San Antonio on June 11 is priced as binary or range-based contracts tied to specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders buy or sell shares reflecting their belief that the actual low will fall above or below defined strike points. Prices move between 0 and 100 cents per share, with the spread between bid and ask reflecting market uncertainty. As June 11 approaches and weather models converge, prices typically tighten, rewarding early accurate forecasters and penalizing those on the wrong side.
The market resolves on Jun 12, 2026, after the lowest temperature recorded in San Antonio on June 11, 2026 is officially reported. Resolution depends on verified meteorological data from a designated weather station or official source covering San Antonio. Once the actual low temperature is confirmed, contracts settle based on whether outcomes matched the pre-defined thresholds. Traders holding positions aligned with the final temperature receive payouts, while those on the losing side forfeit their stakes.
Several factors can shift odds for San Antonio's June 11 low temperature. Updated weather models, particularly those released 7–10 days before the event, often trigger significant repricing as forecasters gain confidence. Seasonal climate patterns, El Niño or La Niña conditions, and historical June temperature data inform trader positioning. Real-time atmospheric changes—jet stream shifts, high-pressure systems, or tropical activity—can alter expectations. Major weather news or unexpected model consensus shifts typically drive sharp price moves as traders adjust positions ahead of resolution.
