Official observations from the Finnish Meteorological Institute (FMI) confirm Helsinki's surface temperature peaked at 18°C around midday on May 13, amid a brief spell of clearer skies and light southerly winds that allowed diurnal heating consistent with early May climatology, where average highs hover near 15–16°C. Current readings have fallen to 10–12°C under increasing cloud cover and showers, with sunset nearing 21:50 local time limiting further warming potential per FMI and ECMWF model consensus. Trader sentiment reflects this skin-in-the-game assessment, pricing 19°C or higher at near-zero implied probability. A realistic challenge would require improbable sudden clearing for late-afternoon solar insolation to push boundaries, though low sun angle and persistent clouds make it unlikely.
