Growing degree days this year
Observed: NOAA GHCN-Daily highs and lows at Reading/Spaatz Field (RDG) (USW00014712), through September 22, 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, Shoemakersville has gathered 3,502 growing degree days on a 50°F base, 313 more than normal by September 22, 2026: about 44 days ahead of the normal season.

| Base | Since Jan 1 | Normal to date | Departure | Normal year |
|---|---|---|---|---|
| Base 50°F | 3,502 | 3,188 | +313 (+10%) | 3,538 |
| Corn, 86/50 | 3,572 | 3,290 | +282 (+9%) | 3,786 |
| Base 41°F | 5,207 | 4,835 | +372 (+8%) | 5,662 |
| Base 32°F | 7,184 | 6,763 | +421 (+6%) | 8,295 |
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).

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 1949. 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.
