What Makes Subtle Differences In Our Summer Weather?
SEATTLE - Tony wondered why is it that the weather is usually different around here, even over short distances. For example, Olympia tends to be hotter than Seattle in the summer.

The difference are mainly due to the mountains and our proximity to the Pacific Ocean and Puget Sound. Olympia gets warmer in the summer because they don't get as much of the cooling effects of Puget Sound. Even in Seattle -- West Seattle tends to be cooler than Capitol Hill and Northgate because they get the sound breezes.

Everett tends to be cooler than Seattle and Olympia because they get the westerly breeze off the Strait of Juan de Fuca in addition to being next to the Sound, adding to the cooling.
