SUMMIT COUNTY — The global temperature in June, averaged from thousands of weather stations, was the fourth-warmest on record for the planet, at 1.13 degrees above the 20th century average, according to the monthly update from the National Climatic Data Center.

Land-surface temperatures measured alone set an all-time record for the month, with the northern hemisphere at 2.34 degrees above average and globally at 1.93 degrees above average. June was the second consecutive month with record global land surface temperatures. The last time June temperatures were below average was in 1976.

In the Northern Hemisphere, it was the third month in a row with record-setting heat over land, with most areas seeing temperatures running well above average. Only northern and western Europe, and the northwestern United States were cooler than average.

In the southern hemisphere, temperatures in Australia remained below average, along with the tip of South America and parts of Antarctica.

With the cooling influence of La Niña gradually fading, ocean temps were also well above average, ranking as the 10th-warmest on record for June. Global temperature anomalies have increased steadily as La Niña fades, from 0.65 degrees above average in January, 0.90 degrees for the January to May period.

The year to-date is the 11th-warmest on record, at 0.52 degrees above the 20th century average.

Extremes prevailed across Europe, with a couple of spots in Austria reporting all-time record highs for any month with a 99.9 degree reading, surpassing the previous record high, set in 2000, by 1 degree.

Farther north, Norway reported its 25th coolest June since record-keeping started in 1900. Parts of eastern Norway reported readings between 3.6 and 4.5 degrees below the monthly average. The UK was also cooler than average by .5 degrees, making in the coolest June since 1991.
