**Trader sentiment for the lowest temperature in Panama City on September 9 remains tightly balanced between 25°C and 26°C because official observations and model guidance placed the minimum squarely in that narrow band.** High humidity, frequent cloud cover, and scattered convective showers—driven by the Intertropical Convergence Zone—suppressed overnight radiative cooling, producing only a modest diurnal range typical of the region’s wet season. Instituto de Meteorología e Hidrología de Panamá forecasts highlighted lowland minima between 21°C and 25°C amid isolated thunderstorms, while real-time station data hovered near 25–26°C. Minor differences in measurement timing, site exposure, or localized rain cells explain the near-even market split, with lower outcomes discounted by the absence of stronger cooling mechanisms.
