Of course that is just the US. The World-Wide temperature in June of 1933 was 0.153 degrees below the 20th Century average. World Wide, the hottest June was in 2010 at 1.05 degrees above the 20th Century Average. June of 2012 hasn’t been released yet.
Let’s look at what the thermometers actually showed in June, 1933. The Earth’s land surface might have had 50% coverage. The error is probably +/- 0.5C. It is spectacularly dishonest to report a global temperature within 0.001 degrees.

Also interesting to note that the current heatwave has been limited to the eastern US, but our friends are saying that it proves global warming. Alarmists want to have it both ways.
