The market-implied odds at 100% for 14°C reflect official meteorological observations confirming this as the verified daily maximum temperature in Helsinki on May 31. Late-spring conditions in southern Finland, influenced by moderate Atlantic airflow and limited solar heating under partial cloud cover, produced readings that aligned precisely with this threshold rather than higher or lower values. Historical climatological data for the period typically show averages near 15–17°C, yet recent pressure patterns suppressed warming enough to cap the high at 14°C. While final agency quality-control reviews could theoretically prompt minor revisions, such adjustments remain rare once preliminary data are validated.
