Recent official forecasts from Russian meteorological agencies and international models indicate Moscow will reach a daily maximum of exactly 21°C on May 23 under partly cloudy skies with light winds, aligning with the market's near-certain 21°C outcome. This positioning reflects verified observational trends and ensemble agreement on limited daytime heating amid springtime conditions near the seasonal average. Realistic challenges include unexpected clearing that boosts insolation and pushes readings higher, or thicker cloud cover and precipitation suppressing the peak by 1–2°C, though current data make such shifts unlikely before resolution.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=UUWW
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
