Ocean temperatures averaged 62.5 degrees Fahrenheit in the June-August period, 1.04 degree higher than normal for the period.

And for August the world sea-surface average was 62.4 degrees, 1.03 higher than usual, also the warmest for August on record, NOAA's National Climatic Data Center said.

The report is based on data back to 1880.
