Climate, weather, they vary.

I've seen accurately-recorded ocean temperature profiles in the tropics and the arctic/antarctic that were WAY above normal, and hot all the way down.

Pockets of warmth are always being swept round in the world's oceans and sometimes a ship ends up in one and measures it.

There are also ones COLDER than normal. For some reason these don't get the same press, these days...

The trick is to measure long-term average temperatures. That takes more than a sensationalist blog, but has a stronger story to tell. The measurements are difficult, but we have to listen to what they say...
