The market predicts a 69.50% probability that Helsinki will reach at least 25°C on June 27, 2026, based on historical temperature trends and seasonal patterns. This aligns with typical late-June temperatures in the region, though variability exists due to climate factors.
A high-pressure system over Scandinavia could bring warm air from continental Europe, pushing temperatures above 25°C. Recent warming trends in the Baltic region also support this outcome, as June 2025 saw similar conditions. Additionally, urban heat island effects in Helsinki may contribute to higher readings.
Unseasonable cold fronts or maritime air masses could suppress temperatures below 25°C, especially if cloud cover or precipitation persists. Historical data shows occasional late-June cold snaps in Helsinki, though these are less common. La Niña conditions might also delay seasonal warming.
