Current forecasts from agencies including the Finnish Meteorological Institute and Met Office indicate a minimum temperature near 11–12°C for Helsinki on August 25, driven by northerly flow and predominantly clear skies that promote strong nocturnal radiative cooling after daytime highs around 18–20°C. Late-August climatology shows typical overnight lows declining toward 9–11°C as solar angles decrease, with model consensus supporting modest cooling absent significant cloud cover or warm advection. The tight clustering of market-implied odds around 9–12°C reflects remaining uncertainty in exact boundary-layer conditions and localized urban heat effects, with new model runs and overnight observations likely to refine the outcome before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 25 Aug '26.
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
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.Current forecasts from agencies including the Finnish Meteorological Institute and Met Office indicate a minimum temperature near 11–12°C for Helsinki on August 25, driven by northerly flow and predominantly clear skies that promote strong nocturnal radiative cooling after daytime highs around 18–20°C.
