National Weather Service - May Through July 2018 Warmest On Record For Lower 48

If you found yourself thinking it was scorching hot in recent weeks, well, you were right. For the three-month period of May to July, the entire contiguous United States (CONUS) “ranked hottest on record,” as the National Weather Service in Los Angeles, California tweeted out Wednesday, adding that “records go back to 1895.”

That map comes from the National Oceanic and Atmospheric Administration (NOAA) report, “Assessing the U.S. Climate in July 2018,” released last week. But NOAA didn’t mention the May-June-July heat record in its report, and that left it to the NWS in Los Angeles to point out the sea of red across the contiguous U.S.

Ed. - Emphasis added.

NOAA did point out that in California in particular, “July was off the charts: The state saw its hottest July and hottest month on record with an average temperature of 79.7 degrees F.”

No wonder the state has been ravaged by deadly, record-smashing wildfires this summer. “At 108.1 degrees F,” NOAA noted, “Death Valley, California, had the hottest average monthly temperature for any recording station in the world.”
