Forecast models from the Servicio Meteorológico Nacional and international sources indicate Mexico City’s September 17 high will likely reach the mid-20s °C, with afternoon peaks between 22–25 °C under partly to mostly cloudy skies and scattered light showers. High elevation near 2,240 m limits surface heating while northeasterly winds and increasing humidity promote convective cloud buildup that caps maximum temperatures. Recent model runs show minor disagreements on cloud timing and rainfall intensity, keeping 24 °C and 25 °C or higher outcomes nearly even in trader pricing. Official observations and updated forecasts later today will resolve the precise peak before evening cooling sets in.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Benito Juárez International Airport Station in degrees Celsius on 17 Sep '26.
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=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.Forecast models from the Servicio Meteorológico Nacional and international sources indicate Mexico City’s September 17 high will likely reach the mid-20s °C, with afternoon peaks between 22–25 °C under partly to mostly cloudy skies and scattered light showers.
