Check the Weather  

Mill Valley, CA – August 19, 2020 – What began as a portal service for agricultural clients has expanded into a suite of elaborate data products to provide critical weather and climate information that empower growers and producers to make confident and informed business decisions. This month’s retrospective looks back upon CustomWeather’s introduction of its weather services for agriculture. 

In 2010, CustomWeather launched an agriculture weather portal to address the specific needs of key clients, including:

  • An online growing degree day calculator
  • Soil moisture and soil temperature forecasts and observations
  • Pest and disease modeling for specific diseases, including powdery mildew and Downy mildew indices for vineyards
