Data-derived climate profile
How Fort Clatsop Natl Mem's climate pattern fits together
heating led · low swing
Heating is the larger measured load in Fort Clatsop Natl Mem, at 4,844 degree days versus 38 for cooling. Unlike a strongly continental record, however, its 19.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Fort Clatsop Natl Mem's frost-free season lasts about 233 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 19.2°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 52°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A moisture-range label is withheld because Fort Clatsop Natl Mem's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Fort Clatsop Natl Mem's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Fort Clatsop Natl Mem, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Fort Clatsop Natl Mem's primary station: FT CLATSOP NATL MEM (USC00353014). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Fort Clatsop Natl Mem; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Fort Clatsop Natl Mem comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
