Resolution hinges on verified meteorological records for San Antonio on that specific date, ensuring an objective and auditable outcome. Once the lowest temperature reading is confirmed, the contract settles according to the pre-defined outcome criteria, and traders' positions are cash-settled based on whether their prediction matched the realized low.
Several factors can shift odds for San Antonio's May 29 low: updated seasonal forecasts, atmospheric patterns (jet stream position, high-pressure systems), historical climate anomalies, and real-time weather model runs released in the days leading up to May 29. Major weather events elsewhere in North America can alter regional circulation. Additionally, any unusual solar activity, ocean temperature shifts, or local urban heat-island effects may influence trader expectations. As May 29 approaches, short-range forecasts become more precise, typically tightening the market range and reducing uncertainty around the final low temperature.
