Trader consensus prices 8°C or higher at a near-certain 100% implied probability, driven by official morning observations from the Finnish Meteorological Institute (FMI) at Helsinki-Vantaa Airport, the market's resolution station, which already exceeded 8°C amid mild spring conditions from a settling high-pressure ridge. Updated FMI hourly forecasts confirm afternoon cooling to around 5°C under light southeast winds and clear skies, locking in the daily peak without potential for significant warmup later. This positioning aligns with early April climatology, where highs average 7–9°C, reinforced by consistent model runs from ECMWF and GFS showing no cold snaps. Realistic challenges are minimal—only an improbable official data revision could shift it below 8°C before end-of-day FMI summary.
