**Forecast consensus points to a typical early-autumn overnight low near 8–11 °C for Helsinki on September 11, 2026, driven by northwest winds advecting cooler maritime air from the Baltic and potential clear skies promoting radiative cooling after recent cloudy, rainy conditions.** Official guidance from sources such as the Finnish Meteorological Institute, Yr.no, and WeatherBug shows daytime highs of 16–18 °C and nighttime minima around 8–10 °C, aligning closely with the 1991–2020 September 11 average (high 16.2 °C, low 10.0 °C). Key variables creating the tight 44.5 % / 44.0 % split between the 16 °C+ and ≤6 °C outcomes include uncertainty in cloud cover—clearer conditions could allow further cooling toward or below 7–8 °C—versus lingering moisture or stronger winds that would moderate temperatures above 10 °C. Model runs remain sensitive to small shifts in steering patterns and timing of any clearing, leaving the exact minimum unresolved until the final hours.

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 11 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.**Forecast consensus points to a typical early-autumn overnight low near 8–11 °C for Helsinki on September 11, 2026, driven by northwest winds advecting cooler maritime air from the Baltic and potential clear skies promoting radiative cooling after recent cloudy, rainy conditions.**
