Official meteorological observations and forecast models from Russia's Hydrometeorological Center established a daytime maximum of 18°C in Moscow on September 13, 2026, under partly cloudy skies with light westerly winds and no precipitation. This outcome aligned closely with pre-event guidance projecting a range of 17–19°C, reflecting typical early autumn conditions slightly above the long-term September average high near 17°C. Real-time station data and model consensus left minimal room for deviation, driving the market's near-certain pricing at 18°C. Only an unexpected post-analysis revision from the primary reporting station or localized measurement anomaly could realistically alter the recorded high.

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=UUWW
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.
