**Trader sentiment for Helsinki's lowest temperature on August 27, 2026, clusters tightly around 10–11°C (45.5% each), with nearby bands at 8–9°C and 12–14°C near 43.5%, reflecting genuine forecast uncertainty just 48 hours out.** Official guidance from the Finnish Meteorological Institute and ensembles shows daytime highs near 19°C under generally benign late-summer conditions, with overnight minima expected in the 9–14°C range. Key scientific drivers include radiative cooling under variable cloud cover, light northerly or variable winds that limit mixing, and the moderating influence of the Baltic Sea on the urban heat island. Small differences in predicted cloud timing or boundary-layer moisture can shift the nocturnal minimum by 1–3°C, explaining why markets price 8°C and 12°C nearly as high as the central outcomes. Historical late-August climatology supports lows near 11–12°C, but current model spreads and the proximity of resolution keep probabilities balanced rather than decisive.

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 27 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
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.**Trader sentiment for Helsinki's lowest temperature on August 27, 2026, clusters tightly around 10–11°C (45.5% each), with nearby bands at 8–9°C and 12–14°C near 43.5%, reflecting genuine forecast uncertainty just 48 hours out.**
