Latest short-range forecasts from the Finnish Meteorological Institute (FMI) and ensemble models like ECMWF project Helsinki's highest temperature on April 18 clustering around 12-13°C at Vantaa Airport, driving trader consensus toward 13°C (42% market-implied probability) amid a high-pressure ridge over Scandinavia ushering mild southerly flow into the Baltic region. This positions 13°C and 12°C (26.5%) as leaders, elevated above mid-April climatological averages of 9-10°C due to light northeast winds (4-5 m/s), minimal cloud cover, and low precipitation risk (<10%). The 20% odds on 14°C or higher capture model spread favoring solar heating under clearer skies, while cooler outcomes reflect uncertainty from potential northerly shifts; new ECMWF/GFS runs and FMI updates expected later today could sharpen these probabilities before resolution.
