A degree day is a measure of heating or cooling. Total degree days from an appropriate starting date are used to plan the planting of crops and management of pests ...
Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature . The estimated average heating energy requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
Sacramento is facing a searing heat wave, but it’s far from the first time the city has encountered extreme temperatures.
Temperatures of at least 105 degrees were recorded for 11 days in a row from July 10 to July 20 and from Aug. 4 to Aug. 14 in 2023, breaking a nine-day streak that held the record since 1923.

One degree day per degree Fahrenheit over 50 °F, or with SI units, degrees Celsius over 10 °C is used. All days during the growing season are then added up, all negative values are set to zero, with the sum of the growing degree-days used to determine the region's classification in the original Winkler index as follows:
The following is a list of Minnesota weather records observed at various stations across the state during the Over 160 years. Minnesota is a state in the Upper Midwestern region of the United States.
