Using NOAA population weight CDD observations, the U.S. weekly population weight CDD was variable – normal and warm – early during summer 2022. The hottest part of summer climatologically is when the hottest weekly CDD count occurred in July. Recently, briefly cooler national CDD was observed. The warm season 2022 finishes somewhat warmer than normal.
