Sand Point, Alaska · field elev 24 ft
Density Altitude at Sand Point (PASD)
Sand Point sits at 24 ft, and even its warmest typical afternoon (August, 57 °F) leaves density altitude around −84 ft — below the field elevation itself. Cold, dense air is the norm here; watch for the opposite altimetry problem on cold days instead.

Frequently asked questions
How high does density altitude get at PASD in summer?
On a typical August afternoon — around 57 °F at the nearest NOAA normals station — density altitude at Sand Point reaches roughly −84 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 PASD on an average day?
It swings with the seasons: from roughly −1,874 ft at the coldest month's average temperature to about −383 ft at the warmest month's — all from a constant field elevation of 24 ft. The month-by-month table above carries the full year.
What is the field elevation of Sand Point?
24 ft MSL, from the FAA NASR airport record (28-day cycle effective 2026-08-06). The identifier is PASD (ICAO) / SDP (FAA), in Sand Point, Alaska.
