My sister, who lives in Tucson, said this chart was shown on the news. This is for spring/summer. I've added the Celsius equivalent temperatures for listers outside of the USA.
  1. 75 F/24 C chilly
  2. 80 F/27 C cool
  3. 85 F/29 C balmy
  4. 90 F/32 C warm
  5. 95 F/35 C warmer
  6. 100 F/38 C hot
  7. 105 F/40 C hotter
    It gets considerably hotter than this. Phoenix is expecting a high this weekend of about 120 F/49 C. This would approach, tie or break the highest temperature ever recorded in Phoenix. I prefer having a real winter to a summer like this.
