The moderating effect of the water also allows for a longer growing season. If there is a pass in the mountain range, winds will rush through the pass with considerable speed due to the Bernoulli principle that describes an inverse relationship between speed and pressure. Orientation should be decided together with massing early in the design process, as neither can be truly optimized without the other. The wind is most often from the south for 3.1 months, from May 2 to August 4, with a peak percentage of 39% on June 3. .
