Recent official forecasts from the Finnish Meteorological Institute and ensemble models show a mild southwesterly flow bringing partly cloudy conditions with showers to Helsinki on August 30, supporting a daytime maximum of 19–20°C as the dominant outcome. This aligns with the market’s leading 20°C (52.5%) and 19°C (34.0%) probabilities, reflecting trader consensus on the current 18–20°C guidance range and limited potential for stronger warming or cooling. Late-August climatology favors highs near 18–19°C under similar maritime air masses, while model spread and rain timing introduce modest uncertainty around exact peaks. Updated runs ahead of resolution will refine these odds.

This market will resolve to the temperature range that contains the highest 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 highest 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 official forecasts from the Finnish Meteorological Institute and ensemble models show a mild southwesterly flow bringing partly cloudy conditions with showers to Helsinki on August 30, supporting a daytime maximum of 19–20°C as the dominant outcome.
