Gullfoss Climate

Understanding the subarctic climate of Gullfoss

Gullfoss enjoys a subarctic oceanic climate typical of Iceland's interior. Located 120 km / 75 miles from Reykjavik, this iconic waterfall is influenced by Atlantic winds and extreme seasonal variations, creating spectacular landscapes depending on the time of year.

Waterfall zone: Humid microclimate with frequent fog generated by the falls
Surrounding plateau: Exposed to prevailing westerly winds, cooler temperatures
Hvítá Valley: Relative protection from winds, more developed vegetation in summer
