Recent official forecasts from the Finnish Meteorological Institute and ensemble models indicate a high near 19–20 °C for Helsinki on August 29, with light southerly flow, partial cloud cover, and only isolated showers expected. This aligns with the late-August climatological decline from peak summer values and current near-normal sea-surface temperatures in the Baltic, supporting the market’s leading 20 °C (39.5 %) and 19 °C (24.5 %) contracts. Traders appear to weigh the narrow spread between these outcomes against minor model differences in daytime heating and wind direction, while the low probabilities assigned to 21 °C or higher reflect the absence of any warm-air advection or clear-sky amplification in the latest guidance. Updated model runs ahead of the 29th will provide the next key data point for resolution.

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 29 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 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.Recent official forecasts from the Finnish Meteorological Institute and ensemble models indicate a high near 19–20 °C for Helsinki on August 29, with light southerly flow, partial cloud cover, and only isolated showers expected.
