Preparing for 2027: Winegrowing in the Year of El Niño

November 18, 2026 - 11:00 AM PST

What Can 2026 Teach Us About the 2027 Growing Season?

With a strong El Niño pattern developing and expected to persist into 2027, winegrowers have reason to pay close attention to winter and early-season conditions. The combination of warming ocean temperatures and the growing season patterns observed in 2026 raises important questions about how vines may respond if another warm, vigorous spring arrives.

As the 2026 harvest unfolded, winegrowers saw the consequences of an unusually early and erratic growing season. Early budbreak, significant heat accumulation in February and March, rapid shoot growth, poor fruitfulness and widespread shatter all contributed to reduced yields in many vineyards.

But what can this season tell us about what lies ahead?

This webinar will take a closer look at the lessons of the 2026 growing season and explore what they could mean for vineyard management in 2027. We’ll examine how temperature patterns influenced phenology, fruitfulness, fruit set and berry development, and why conditions occurring well before harvest can have such a significant impact on final yields.

We’ll also discuss what growers should be watching as the 2027 season approaches, including the potential implications of El Niño, early heat accumulation and spring weather variability. From pruning decisions to monitoring vine development, understanding the signals from 2026 can help growers prepare for a potentially challenging year ahead.

Join us for a practical discussion of the weather, vine physiology and management considerations shaping the 2027 winegrowing season—and learn how the lessons of 2026 can inform decisions in the vineyard before the next growing season gets underway.

Registration is now open. Join us for a practical, forward-looking conversation designed to help growers head into 2027 better prepared for what the season may bring.
