In the winter, the Kitsap peninsula is one of the wettest places, but often it seems to be one of the driest places in late spring or summer-why?

 

The lows that approach western Washington in late autumn through early spring are preceded by south to southeast winds. This is a consequence of the counter-clockwise circulation around such lows. Those winds carry moisture up the south and east slopes of the Olympic mountains, which amplifies rainfall....both over Hood Canal and nearby Kitsap county. However as the lows become less frequent from late spring through early fall, rainfall instead often comes from weak disturbances moving from the west; the Olympic mountains produce 'rain shadowing' over the Kitsap peninsula in such patterns that bring southwest to westerly winds. Heavier rain showers tend to occur east of Puget Sound.
