Recent forecasts for Panama City, Panama, indicate a daily maximum near 29–31°C on September 18, driven by typical late-wet-season conditions with high humidity, scattered convection, and light winds that limit extreme heating. Model consensus from regional guidance shows modest variability tied to the timing and coverage of afternoon thunderstorms, which can cap temperatures through evaporative cooling or allow brief spikes under clearer breaks. Historical September averages near 29°C provide context, while the spread across 28–33°C outcomes reflects uncertainty in exact peak timing relative to official measurement windows. The 34°C-or-higher bin remains plausible only under drier, sunnier deviations not currently favored by ensemble runs. Updated short-range model outputs and local station observations in the next 48 hours will refine these distinctions.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=mpmg
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
