The market suggests a low probability (17.55%) that Helsinki's highest temperature on June 29, 2026, will reach 23°C. Historical climate data and seasonal trends indicate this is unlikely, though not impossible.
A rare heatwave in late June could push temperatures to 23°C, driven by high-pressure systems from continental Europe or prolonged southerly winds. Climate change may slightly increase the likelihood of such extreme events.
Historical averages for Helsinki in late June show highs typically around 18-21°C, with 23°C being an outlier. Persistent maritime influence or cloud cover would likely keep temperatures below this threshold.
