We have had a mild, average summer so far, with temperatures in the high 60s or 70s (18 to 24 °C). The sun still sets after 9 pm .. so even after dinner, there is still lots of time to go for a walk or to water the garden.
In the South and Southwest of the United States a phenomenon called a ‘heat dome*‘ has developed, which will lead to historic high temperatures the next few weeks. It is possible for Phoenix, AZ, to see 120 °F (48 °C).
*A heat dome occurs when strong, high-pressure atmospheric conditions trap hot ocean air like a lid or cap.
