There used to be real-time buoys but one by one they were destroyed by boaters and other acts of vandalism (one was actually shot up according to the UW guys).
For near-time reports you are better off asking people that went out recently - the lag time on what remains out there makes it pretty useless unless you want to use the data to check trends.
I have a reliable source that told me Sunday : They had an average temp from Rainier Beach to Kenmore of 46*. I was fishing deeper water from docks and he calls me up to tell me he had caught a 3# largemouth in 2' of water. Of course I was skeptical until he showed up and produced the pics. Needless to say, I still run amok in skunkdom. Sooooon!
