on the north. Wahluke Slope has one of the driest, warmest climates in the state, allowing nearly complete control of vine vigor and ripening through irrigation. The entire 81,000-acre appellation sits on a large alluvial fan, making the soils notably uniform over a large area. The topsoil is deep, wind-blown sand with a depth, on average, of more than 5 feet (150 cm). This provides both ample drainage for vinifera vines and greater uniformity in plant vigor and ripening than seen in other areas of Washington. The major distinguishing feature of the Wahluke Slope is its uniformity in aspect, soil type, and climate. The entire appellation lies on a broad, south-facing slope with a constant, gentle grade of less than 8%. This, along with the proximity to the Columbia River, helps minimize the risk of frost, which can affect other areas of the state. The highest temperature ever measured in Washington state, up until 2021, was recorded at Wahluke on July 24, 1928, at . This record was later tied at Ice Harbor Dam in 1961. The temperature was eventually surpassed on June 29, 2021, when Hanford reached . The area is largely within the
