The observed daily maximum of 31°C at monitoring stations in Panama City aligned precisely with the market's dominant outcome, reflecting typical September conditions in the region's tropical climate where average highs hover near 30°C amid high humidity, consistent trade winds, and scattered convection during the rainy season. Official forecasts from regional models showed minimal day-to-day variability, with no significant shifts from Atlantic moisture patterns or El Niño influences to push readings higher or lower. Trader consensus at 100% for 31°C thus captured the narrow range of verified measurements, though minor station-specific discrepancies or localized cloud cover could theoretically have altered the exact peak by 1°C.
