Recent short-range forecasts from the Finnish Meteorological Institute and Met Office indicate daily maxima near 20–21°C for Helsinki on August 10, consistent with the market’s clustering around 22°C (32.5% implied probability) and 21°C (16.5%). Key variables include cloud cover and any embedded showers that could suppress peak readings, steering winds from the Baltic or Atlantic that modulate advection of warmer air, and local urban heat-island effects versus airport observations used for resolution. Ensemble spread remains wide due to typical summer variability in mid-latitude flow, with lower-probability tails (25°C or above at ~3%) requiring clearer skies and stronger southerly flow while sub-20°C outcomes hinge on increased precipitation or northerly intrusions. New model runs and FMI updates over the next 48 hours will likely tighten the distribution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 10 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Helsinki Vantaa Airport Station, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
