Globally, June 2017 ranked as the fourth warmest June on record for land/ocean combined. Records go back as far as 1880.
June 2017 averaged 0.69 degrees C above the 1951-1980 mean.
The NASA graph below shows global temperature anomalies since 1950. The three symbols at the bottom of the top image are major volcanic eruptions that produced a brief, but significant cooling influence on planet. The bottom graph shows the plots of El Nino (red) and La Nina (blue) episodes over the past 65+ years. El Nino's typically have a warming influence on global temperatures and La Nina's usually have a cooling influence.

ENSO (El Nino Southern oscillation) conditions remain neutral at this current time and are favored through the fall, but there is also a chance that it will turn into a weak El Nino.
In the Northern Hemisphere, June 2017 averaged 0.91 degrees C above average, making last month the third warmest June on record.
In the Southern Hemisphere, June 2017 averaged 0.49 degrees C above average, making last month the fourteenth warmest June on record.
