Recent forecasts from multiple models indicate Mexico City highs on September 19 are most likely to reach 24–26°C amid typical late-summer conditions, with scattered cloud cover, light winds, and a 30–70% chance of showers that limit afternoon heating. This range aligns with the market-implied probabilities favoring 25°C or 26°C+, reflecting the consensus from updated runs showing modest instability rather than clear skies or strong ridging. Historical September maxima average near 24°C, and current observational trends plus short-range guidance suggest limited deviation unless drier air arrives or convection suppresses earlier than expected. Updated model outputs and official agency briefings over the next 48 hours will refine these odds ahead of market resolution.

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.
