Growers Prepare for 2027 Season Amid Record El Niño Forecast; Early Harvest Trend May Become Permanent

Challenges from the 2026 growing season—early heat accumulation, poor fruit set, and reduced yields—offer lessons for 2027, when a record-strength El Niño is forecast to take shape. Industry experts suggest the upcoming season may bring fundamental shifts in viticultural phenology.
The Wine Industry Network has opened registration for the final session of its Growing Forward conference series, scheduled for November 18, 2026, bringing together weather, vine physiology, and vineyard management experts to discuss lessons from 2026 and challenges ahead for 2027. The timing reflects unusual urgency within the industry, as growers navigate unprecedented conditions.
The 2026 growing season presented North Coast winegrowers with early heat accumulation that accelerated vine development. However, this advancement came with complications: many vineyards experienced poor fruitfulness, reduced fruit set, and lower overall yields. Looking ahead, forecasters point to an even more significant challenge—a record-strength El Niño formation taking shape for the coming year.
Phenology and Atmospheric Connections
During the November 18 session, experts will examine the relationships between early-season temperatures and key viticultural processes: vine development timing, fruitfulness, and fruit set. Understanding these connections is critical, as growers must make strategic decisions about pruning and early-season monitoring based on the atmospheric signals they observe during winter and spring. The conditions to watch this winter and spring will directly inform vineyard management choices.
Industry observers have noted that the emerging pattern suggests early harvests may shift from anomaly to norm. This indicates that fundamental vineyard management practices—from pruning strategies to the timing of the entire vegetative cycle—could undergo long-term transformation. The phenological changes now becoming apparent may require growers to rethink established protocols that have governed operations for decades.
Adaptation and Industry Response
For growers preparing for 2027, adaptation represents a pressing imperative. The discussion at Growing Forward will work toward practical recommendations and guidance to help winegrape cultivators navigate the new conditions. The free conference aims to provide actionable insights that vineyards can implement as they adjust to what appears to be a shifting climate pattern. Early preparation and strategic adjustment now may prove essential for managing the challenges the 2027 season will bring.
