According to data just updated by NASA, last August was the warmest August for the entire instrumental data record, which begins in 1881. This has been something of a mixed year but overall warm. Of the 134 years for which there are data, the coolest month this year so far was February, at 17th place, with July also being cool, at 11th place. Keep in mind this is over 134 years. For the months of January through August, there are no one-digit ranks (1 through 8) prior to 1989, inclusively, and you don't really start getting consistent "top ten" ranks until 1998.

Monthly ranks so far this year, January was 4th, Feb was 17th, March was 4th, April was 2nd, May was first, June was 3rd, July was 11th, and as noted, August is 1st. For a year in which we are not (yet) experiencing an El Niño, that is very, very warm.

Again, these are global temperatures. Your local mileage may vary.

We don't know how 2014 will rank as a year. If there is no El Niño it will rank high. If an El Niño gets going soon enough to affect the year's average, 2014 may well be in the top few warmest years since global warming began.

Here is where the year to day (Jan through Aug) stands in relation to the years in the data set since 1990 inclusively:
