The river is not really relevant. The Green is regulated, any snowmelt is first trapped behind Seattle's Howard Hansen Dam and then gets released (from depth). A day or 2 of hot weather doesn't change its temp much. Current temp is around 7 to 8C in Tukwila (very close to Elliot Bay's temp).

Additionally, the general (net) circulation pattern in Elliott Bay is counterclockwise. "Up" along the waterfront, west along Magnolia. That combined with the fact that even in August the Duwamish can only create a very thin sliver of marginally warmer, less salty, less dense water on the surface means it doesn't do much overall.
Lots of things cool the Sound off. The big driver warming it up is daytime solar radiation, both short and longwave. Basically the same engine warming up streams and lakes.

I made it to the Lake yesterday, temperatures were up 3 degrees (48->51) all the way down to 50 feet as compared to last weekend.
