Data used in this study corresponded to daily records of milk production and climate variables obtained from a weather station located at the Austral Agricultural Experimental Station (EEAA). The periods of data analysis were considered from December 1st to March 1st of the seasons 2012-2013, season 2015-2016, and season 2016-2017. Hourly records of ambient temperature (ºC), relative humidity (%), wind speed (m/s), and solar radiation (W/m2) were obtained from the weather station located at the EEAA. The dairy farm has approximately 90 ha with a herd of 180 Holstein Friesian dairy cows. The farm has a bi-seasonal calving season (autumn and spring). Cows calving in autumn had an average yield of 22.0 L/cow/day obtained, this figure increases in the case of spring-calving cows, where an average yield of approximately 26.0 L/cow/day is obtained. The feeding of the animals is mainly based on pastures plus concentrates supplied during the two daily milking’s. In addition, depending on the year, cows are offered grass silage as well as summer turnips in the summertime. The climate of the area is temperate-humid with a Mediterranean influence. The average annual temperature is 12°C. Annual precipitation exceeds 2,200 mm/year, but it has a very uneven temporal distribution. During the summer months, in general, water losses by evapotranspiration exceed contributions by precipitation. Cows' individual milk production data, per milking and day, were obtained from the ALPRO software installed in the milking parlor of the EEAA. All the data were entered into an Excel spreadsheet, obtaining the averages of temperature, relative humidity, wind speed, and solar radiation of the daily period between 12:00 PM and 19:00 PM were used.
