Weather & Climate
Understanding the Conditions That Shape Our Wines
High in the foothills of the North Georgia mountains, Three Sisters Vineyards sits within the Dahlonega Plateau AVA, a region known for its unique combination of elevation, mountain airflow, and mineral-rich soils. To better understand the climate that shapes each vintage, Three Sisters hosts a University of Georgia agricultural weather station directly on the vineyard property. This station is part of the Georgia Automated Environmental Monitoring Network (AEMN), a statewide system that collects precise weather data used by farmers, researchers, and agricultural specialists throughout Georgia. Because the station sits here on the vineyard, the data reflects the actual conditions experienced by our vines each day of the growing season.
A Research-Grade Weather Station in the Vineyard
The UGA weather station continuously records environmental conditions that influence grape growing and vineyard management.

The weather station at Three Sisters Vineyards offers a live look at the conditions that shape the growing season on our property. Because the station is located here in the vineyard, the data reflects the real-time environment our vines experience each day, from airflow and humidity to temperature shifts and cloud cover.
For a vineyard, these measurements are more than simple weather updates. They help illustrate the seasonal rhythm of the Dahlonega Plateau and the natural conditions that influence vine growth, fruit development, and harvest timing throughout the year.
Climate of the Dahlonega Plateau
Growing seasons of roughly 190–200 days
Warm sunny days during summer
Cooler mountain evenings that help preserve acidity
Good airflow across the hillsides

Why It Matters for Wine
Great wine begins in the vineyard, and weather plays a major role in how grapes develop, ripen, and are harvested.
Frost Risk
Protecting Buds
Early spring frosts can damage young buds. Careful temperature monitoring helps vineyards anticipate and respond to cold events during this critical stage of growth.
Growing Degree Days
Tracking Ripeness
Heat accumulation across the season influences how quickly grapes ripen and how flavors develop. Tracking these conditions helps guide vine growth and fruit maturity.
Humidity & Rainfall
Vine Health
Humidity and rainfall affect disease pressure in the vineyard. Monitoring these conditions helps maintain vine health throughout the growing season. We plant on hills to control water flow.
Harvest Timing
The Perfect Moment
As grapes approach maturity, weather patterns help guide harvest decisions for the ideal balance of flavor, acidity, and structure. We keep a keen eye on weather patterns daily.
