Current ensemble forecasts from agencies like the Finnish Meteorological Institute and ECMWF indicate a minimum temperature in Helsinki on August 29 most likely between 12–15°C, driven by southeasterly winds advecting milder maritime air, extensive cloud cover reducing nighttime radiative cooling, and light precipitation potential. This setup limits the typical August nocturnal drop compared to clearer anticyclonic conditions earlier in the week. Trader consensus clusters tightly around 12–14°C because model runs show modest spread in cloud timing and wind mixing, with lower probabilities assigned to extremes below 11°C or above 16°C given historical climatology and stable large-scale patterns. Updated model guidance over the next 48 hours will refine these thresholds ahead of market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
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.
