**Trader consensus has locked onto 25°C as the highest temperature recorded in Mexico City on August 28, 2026, reflecting verified observations from official meteorological stations in the Valley of Mexico.** Late-summer conditions featured typical afternoon convection, moderate cloud cover, and high-altitude effects that limited daytime warming, producing a maximum aligned with seasonal averages around 23–26°C. Forecasts from sources such as the Servicio Meteorológico Nacional and station data consistently pointed to highs near 24–26°C before final readings confirmed 25°C. This outcome aligns with historical patterns for the period, where rain-cooled air and elevation prevent frequent extremes above 28°C. Only a significant station discrepancy or revised official report could alter resolution, though such revisions are rare once daily summaries are issued.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
