2016 Growing Conditions Report

The Growing Conditions Report, produced in cooperation with Pacific Geodata, Picovale Weather Service, and Premiere Viticultural Services, contains maps, tables, and graphs depicting regional Napa climate data and will provide a countywide overview of general growing conditions.

The report employs three simple and widely understood climate measurements known to influence grapevine development, ripening, and crop loads: 

• Growing degree days (GDD)
• Total frost hours
• Rainfall  

Additionally, the report provides data for previous growing seasons (starting in 2009), allowing grapegrowers to compare conditions across vintages.  Over time, a multi-year collection of reports will add to our understanding of regional climate conditions and help to identify climate trends.  This year, we will also take an in-depth look at two weather events that shaped the 2016 vintage providing case studies and highlights to the 2016 report. Attendees will receive a copy of the report at the seminar.
