Chris, the oceans are acting as a check and regulating the high temperatures for us (somewhat at any rate). Our decade for most number of 90 degree days was the 90s. Or to be more precise, 1991 to 2002. We haven't seen a consistently super hot summer since 2010 and before that it was 1993 that set all our records (and 1983 before that.)
I don't believe it's an accident or a fluke that we're seeing more seabreeze summers, this is the ocean's response to what we're doing to the climate. The planet always seeks to find a balance.
