JACKSONVILLE, Fla - July 2019 has replaced July 2016 as the hottest month on record, with meteorologists saying that global temperatures marginally exceeded the previous record.

The European Union's Copernicus Climate Change Programme, which analyzes temperature data from around the planet, said that July was around 0.56 °C warmer than the global average temperature between 1981-2010.

Locally, we did not see record-breaking heat for the month of July, but we did barely top out above average heat for the month. Over average high for the month of July this year was 92.3, only slightly above the normal of 92.0. 

We did not even come close to breaking our all-time daily high-temperature record for the month of 104° set on July 11th, 1879. Our hottest day this month this year was 99° which we hit on July 2nd and again on the 3rd. 

Returning to a more global focus of the month's temperatures, the previous record for July, set in 2016 was during a much hotter weather pattern globally than we are experiencing this year. 

July 2016's high-temperature record was in the throes of one of the strongest El Niño events on record.

El Niño events are characterized by warming of the ocean waters in the Pacific Ocean and have a pronounced warming effect on the Earth's average temperature.

Though there was a weak El Niño in place during the first part of 2019, it is transitioning to a more neutral phase, making the extreme July temperatures even more alarming.

Nobody should be surprised given the rate of unprecedented heatwaves and record warm spells lately. In fact, the previous hottest global month on record was June 2019.  

According to data from NASA and the National Oceanic and Atmospheric Administration (NOAA), nine of the 10 warmest years on record have occurred since 2000.

Florida has felt the meltdown. The Sunshine State just had its hottest May on record since record-keeping began in 1895. Then came June, which ranked as the third-warmest in the state's history. 

Jacksonville Beach had the hottest July on record which dates back 73 years with an average temperature of 84°.

July average temperature rankings for the south east puts Jacksonville Beach at the top.

The biggest increase in average temperatures is coming from warm nighttime temperatures, not daytime ones.

NOAA says 2019 is almost certain to end up as one of the three warmest years on record.
