Larsen Bay, Alaska · field elev 87 ft
Density Altitude at Larsen Bay (PALB)
Larsen Bay sits at 87 ft, and even a typical August afternoon (63 °F) only lifts density altitude to about 375 ft — heat still trims performance, but the field rarely turns high-and-hot.

Frequently asked questions
How high does density altitude get at PALB in summer?
On a typical August afternoon — around 63 °F at the nearest NOAA normals station — density altitude at Larsen Bay reaches roughly 375 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 PALB on an average day?
It swings with the seasons: from roughly −1,767 ft at the coldest month's average temperature to about −39 ft at the warmest month's — all from a constant field elevation of 87 ft. The month-by-month table above carries the full year.
What is the field elevation of Larsen Bay?
87 ft MSL, from the FAA NASR airport record (28-day cycle effective 2026-08-06). The identifier is PALB (ICAO) / 2A3 (FAA), in Larsen Bay, Alaska.
