Recent forecasts from multiple models, including those referenced by the Finnish Meteorological Institute, indicate a mild overnight low near 15°C in Helsinki on August 30, driven by persistent cloud cover, light southwesterly winds, and a humid air mass that limits radiative cooling. This aligns with the market's strongest implied probability at 15°C, as daytime highs hover around 18–19°C amid scattered showers. August 2026 has run slightly below the 1991–2020 climatological average low of 11.9°C for the date, with recent days featuring similar overcast conditions that have moderated temperature drops. Traders appear to weigh these factors against minor model spread in the exact minimum, with resolution hinging on official observations from Helsinki stations overnight.

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 30 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 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.
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.Recent forecasts from multiple models, including those referenced by the Finnish Meteorological Institute, indicate a mild overnight low near 15°C in Helsinki on August 30, driven by persistent cloud cover, light southwesterly winds, and a humid air mass that limits radiative cooling.
