Density Altitude at Nightmute (PAGT)
Nightmute sits at 7 ft, and even a typical July afternoon (64 °F) only lifts density altitude to about 328 ft — heat still trims performance, but the field rarely turns high-and-hot.

Frequently asked questions
How high does density altitude get at PAGT in summer?
On a typical July afternoon — around 64 °F at the nearest NOAA normals station — density altitude at Nightmute reaches roughly 328 ft at standard pressure. Hotter-than-normal days, low pressure, and humidity all push it higher, so run the day's actual numbers before flying.
What is the density altitude at PAGT on an average day?
It swings with the seasons: from roughly −3,634 ft at the coldest month's average temperature to about −152 ft at the warmest month's — all from a constant field elevation of 7 ft. The month-by-month table above carries the full year.
What is the field elevation of Nightmute?
7 ft MSL, from the FAA NASR airport record (28-day cycle effective 2026-08-06). The identifier is PAGT (ICAO) / IGT (FAA), in Nightmute, Alaska.
