Folldall Fredheim, Norway´s Oymyakon: -4,2°C, TOP5 Coldest June Temperatures since 2010

Marek Kučera June 13, 2025 2 min read

On a chilly June 12th morning in 2025 (Thursday), Folldall Fredheim, a highland weather station in Norway’s Innlandet county (694 MASL), registered a minimum temperature of –4.2 °C, making it one of the coldest June nights in over a decade.

❄️ Unusually Cold for June

Folldall Fredheim, situated at 694 meters above sea level, is no stranger to brisk nights. However, –4.2 °C in June is exceptional, even by mountain standards. Based on climatological data from 2010 to 2024, average June minimum temperatures at this station typically range from +2.0 to +6.5 °C, depending on year and pattern.

This means the 2025 reading was 6 to 10 degrees below the average nightly low for the time of year.

The –4.2 °C minimum in June 2025 clearly stands out—likely one of only a few June readings below –3 °C since modern records began at the site.

🧭 “Norway’s Oymyakon”?

Folldall Fredheim has gained a quiet reputation as one of Norway’s coldest inhabited regions outside winter. The recent June event reinforces that nickname, referencing Oymyakon in Siberia, the coldest inhabited place on Earth. Of course, Folldall is far milder in winter, but its ability to radiate heat efficiently on clear, calm nights, even in summer, puts it in a class of its own.

🧬 Why So Cold?

Meteorologists attribute this rare event to a strong radiational cooling setup:

Clear skies overnight
Dry air and low dew points
Lingering snow patches nearby
Weakening westerlies and calm conditions

Such setups are ideal for rapid nighttime cooling in valleys like Folldall.

🐝 Impacts & Implications

Agricultural sensitivity: June frost can damage sensitive crops, especially fruit blossoms and early vegetables.
Climate signal: While the globe warms on average, extreme local cold snaps still occur due to atmospheric variability.
Tourism/weather awareness: Hikers and campers in inland Norway must remain prepared for sub-zero temperatures—yes, even in June.

🧊 Coldest June Minimums at Folldall Fredheim Since 2010 (Est.)

🌍 Final Thought

The –4.2 °C reading at Folldall Fredheim is not just a local curiosity—it’s a powerful reminder of how topography, air mass, and timing can produce near-winter conditions deep into summer. As the climate warms, paradoxically, rare cold extremes like this may become sharper and shorter, rather than disappearing entirely.
