What?!? This is nonsense. The monsoon season starts when the humidity goes up. Looks like the NWS is dumbing down the definition. Why not call it “summer” ?? The weather folks have never been able to predict when the monsoon will start and when it will end. By redefining it as a simple date range they might get their predictions right.
Those of us who have lived in AZ for a while (31 years for me) KNOW this is BS.
One of my dogs, Annie, a Labrador Retriever mix, thinks summer started this weekend. When I brushed her, sheets and sheet of shed hair came off her. She is preparing her summer wardrobe.
