Idaho saw its summer temperatures rise sharply in June and continue through the months of July and August with temps regularly over 90 degrees— often climbing to triple digits. Climate research has found higher average temperatures are increasing, and the EPA reports that heat waves have increased in intensity, frequency, and duration over the last fifty years. For Idaho wine growers, like Mike Williamson of Williamson Orchards and Vineyards, the heat of the past few summers is a growing concern. “I kind of obsess a little bit over the 10-day forecast,” he says. “So, if something’s on the horizon, we start taking action to get ready for it now.”
