Alsace experiences dry conditions with warm summers primarily due to its unique geographical positioning. The region is located in northeastern France, bordered by the Rhine River, which serves as a natural barrier. This positioning allows Alsace to benefit from a rain shadow effect, as the Vosges Mountains to the west block moisture-laden winds, leading to reduced precipitation.

The warm summers are a result of the continental climate prevalent in the area, which contributes to the accumulation of heat during the growing season, making it favorable for grape growing. The combination of these factors creates an environment conducive to producing high-quality wines, particularly white varietals like Riesling, Gewürztraminer, and Pinot Gris, which thrive in such climates.

In contrast, other options do not accurately reflect the climatic realities of the region. Cold and wet conditions would not support the types of vineyards found in Alsace, nor would humid and tropical weather align with the cooler continental climate. Likewise, cool and coastal conditions do not apply, as Alsace is landlocked and distanced from coastal influences that would typically provide more humidity and precipitation.
