While this summer has been quite pleasant for most of the Southeast for the majority of June, other parts of the country and world have not been so fortunate. Many locations observed very high temperatures sometime during the month, including Puerto Rico early in June, the upper states in mid-June, and Texas in late June. As we enter enter mid-July, a new heat wave is setting up in the western United States and is expected to last for at least a few days but could be longer if the pattern locks in place. This could bring extreme temperatures to many areas of the Western US, causing significant impacts on agriculture and water supplies. You can read the monthly climate summary headlines at June marked by record-setting U.S. heat waves, severe weather | National Oceanic and Atmospheric Administration (noaa.gov) and look at the statistics at Assessing the U.S. Climate in June 2023 | News | National Centers for Environmental Information (NCEI) (noaa.gov).
Note that even though our mean June temperatures are shown as near normal, the state rankings of temperatures for the year as a whole are still in the top ten warmest because of the combination of some very warm months like February combined with a much higher 30-year normal than in the past due to the upward rise in temperature over time due to global warming.
