Depends on how you define great weather. It doesn't rain nearly as much as people assume (lived there 6 years), but most days have some light drizzle. For a tennis player, that is emotionally taxing (is it going to rain? should we make plans).
I moved to Seattle and it's not the rain that bothers me (it's really not as bad as people say, even during the winter months), it's the cold. .. or rather lack of hot.
It never gets above 26C here. There are plenty of other cities like this (London just had a record heatwave .. of 29C; seriously that's too hot for them. People were passing out in the toobs. Wellington, another coastal city, has people bitching when it gets up to 27C as too hot), but the difference is they do get warm .. for an extended period of time. From May through August (opposite in Wellington cause hemispheres), you know you can put your jacket away. You don't need it. At worst it's gonna be a little refrigerator like if you stay out too late.
In Seattle, it could be mid-June and you might need that jacket...at noon, and then the next day you'll be burning up.
While I miss the seasons a little bit (mainly thunderstorms and snow for a little bit), Seattle is WAY better than the midwest. I'll gladly take mild weather over hot humid summers and winters so cold all you see during the winter outside are bundles of clothing walking around.
