Current forecasts from multiple meteorological models project overnight lows of 12–14°C in Mexico City for September 15, driven by typical early-fall conditions with moderate cloud cover, light winds, and scattered showers from the ongoing rainy season. No strong cold fronts or unusual cooling signals appear in recent model runs, keeping temperatures near the September climatological average. This consensus centers probabilities on mid-range outcomes, though traders appear to weigh residual uncertainty from model spread on exact radiative cooling under variable cloudiness versus any late intensification of precipitation. Updated short-range guidance and local observations in the next 48 hours will refine the minimum temperature before market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=mmmx
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.
