Juvvasshøi or Juvvasshøe is a mountain in Lom Municipality in Innlandet county, Norway.

This value is extrapolated from a larger number of official Norwegian weather stations.

[3] According to the experience in other alpine and polar regions this MAAT indicates that permafrost must be widespread and probably extends to a depth of several hundred meters.

Within the EU-sponsored project PACE (Permafrost and Climate in Europe), a 129 meters deep vertical borehole in bedrock was drilled in August 1999 on Juvvasshøi at an altitude of 1893 meters above sea level.

Juvvasshøi is surrounded by several other notable mountains of Jotunheimen including Glittertinden to the east, Galdhøi and Galdhøpiggen to the southwest.
