How does the temperature range throughout the day in the Spring Mountain District typically behave?

The Spring Mountain District is known for its unique climate characteristics, which include a relatively low diurnal temperature range. This means that the temperatures do not vary significantly between day and night. This behavior can be attributed to several factors, including the district's elevation and its proximity to bodies of water, which tends to moderate temperature fluctuations.

In vineyards, a low diurnal range is often beneficial because it helps preserve acidity in grapes while allowing for slower sugar accumulation. This balance is crucial for producing high-quality wines, which is a hallmark of the Spring Mountain District. Understanding the thermal dynamics in this area is essential for evaluating its suitability for growing various grape varieties. The other options suggest varying degrees of temperature fluctuation, which do not accurately reflect the climatic conditions typical of the Spring Mountain District.
