I did some further research after I sent out that plot that Mary Sue put on the wiki, and discovered that there is a region surrounding the Puget Sound/Strait of Georgia that is in the rain shadow of the Olympic Peninsula/Vancouver Island mountains, that exhibits the classic U-shape when you plot the monthly rainfall averages over the entire year. A number of towns up there get less than 0.5 inches of rain in July. In fact it is surprising that even the total annual rainfall, average, isn't all that high in a region roughly bounded by Seattle in the south and Vancouver (BC) and Nanaimo in the north and Port Angeles to the west. If you get much outside of this roughly triangular area surrounding and close to the water (of the Sound or the Strait) in any direction, the annual rainfall rapidly rises to amounts that are very stereotypical of the Pacific Northwest (70 inches and above). Even the wettest areas in this triangle don't get more than about 40 inches of rain total during the entire year and only get at most 1 inch of rain during the month of July. And the areas right along the coast tend to be USDA zone 9a (which I think is the coldest zone where you can reasonably expect mediterranean bulbs to grow well since they do most of their growing in the wintertime when the rains happen. Some examples of the total annual rainfall (in inches): Nanaimo - 43 Vancouver (BC) - 43 Seattle (airport) - 38 Blaine - 40 Bellingham - 34 Anacortes - 25 Victoria (BC) - 27 Port Angeles - 24 Port Townsend - 18 (This last is surprising because in comparison, downtown Los Angeles gets 15 inches a year, UCLA on the west side of L.A. gets 18, while some of the inland southern Calif. valleys actually get more than Pt. Townsend: the Pasadena area (where the famous Huntington Gardens are) gets 19 inches for example.) --Lee Poulsen > >Mary Sue >PBS List Administrator and TOW Coordinator > >Mary Sue Ittner >California's North Coast >Wet mild winters with occasional frost >Dry mild summers >
