Recent surface observations from Moscow meteorological stations confirm a daily maximum of 18°C on September 5, 2026, under overcast skies with periods of rain and a southwesterly flow that limited diurnal warming. This aligns with National Weather Service-equivalent forecasts and GFS model output showing suppressed highs near the long-term September average of roughly 18.5°C due to persistent cloud cover and precipitation. Trader consensus at 100% implied probability reflects the tight clustering of verified readings around this threshold, with minimal upside potential from clearer conditions or downsides from cooler advection. Only a substantial post-analysis revision in official station data could alter 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=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.
