Frequently asked questions

How high does density altitude get at PG1 in summer?

On a typical July afternoon — around 80 °F at the nearest NOAA normals station — density altitude at Griffin Field reaches roughly 1,637 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 PG1 on an average day?

It swings with the seasons: from roughly −2,534 ft at the coldest month's average temperature to about 947 ft at the warmest month's — all from a constant field elevation of 200 ft. The month-by-month table above carries the full year.

What is the field elevation of Griffin Field?

200 ft MSL, from the FAA NASR airport record (28-day cycle effective 2026-08-06). The identifier is PG1 (FAA), in Levant, Maine.
