**Mild, rain-soaked conditions are pinning Helsinki’s minimum temperature near 11–12 °C today.** Persistent cloud cover, light-to-moderate rain, and a southeasterly flow of maritime air have limited overnight radiative cooling, keeping surface temperatures elevated compared with the long-term average low of ~8 °C. Official guidance from the Finnish Meteorological Institute and ensemble forecasts converge on a nighttime floor of 11–13 °C, with little model spread that would support either sub-10 °C readings or a climb above 12 °C. Traders therefore assign nearly equal implied probabilities to the 10 °C, 11 °C, and 12 °C outcomes, reflecting the narrow uncertainty band around the consensus minimum and the absence of any late-day cold-air advection that could shift the result.
