Growing degree days this year

Observed: NOAA GHCN-Daily highs and lows at Ainsworth Munici (ANW) (USC00250050), through September 23, 2026; GHCN trails the calendar by a day or more. Normal: NOAA’s 1991-2020 daily normals at the same station, NCEI’s own for base 50°F and the corn method, and for bases 41°F and 32°F computed here from NCEI’s daily mean and its standard deviation (Thom’s method).

Since January 1, Bassett has gathered 3,070 growing degree days on a 50°F base, 158 more than normal by September 23, 2026: about 17 days ahead of the normal season.

Base 50°F: The common base for warm-season crops, turf and most insect models; USA-NPN’s pest forecasts use it. Corn, 86/50: Modified growing degree days for corn: highs above 86°F count as 86 and lows below 50°F as 50 (Barger 1969; Purdue Extension). Base 41°F: 5°C, the base used for cool-season crops such as alfalfa and canola. Base 32°F: 0°C, the base USA-NPN uses for its accumulated temperature maps and for its hemlock woolly adelgid forecast. A day adds its mean temperature, (high + low) / 2, above the base; the corn method first holds the high and low between 50°F and 86°F. Corn typically needs 100 to 120 of those units from planting to emergence (Purdue Extension). The station missed 46 days this year; they are counted at normal.

What this means

A normal is the average of the thirty years 1991 to 2020, the period the World Meteorological Organization and NOAA use for comparison. It is an average, not a forecast: most days depart from it, and some by a long way.

A record is the highest or lowest value on the date in every year the station has reported, back to 1905. It rests on one station, so a neighbor a few miles away can hold different ones.

Cloud, humidity, wind and sunshine come from a reanalysis: a weather model run over the past with every observation fed in, averaged over a grid cell about 50 km across. It is consistent everywhere on Earth; it smooths local detail such as a lake shore or a valley.
