If phoenix, arizona, experiences a cool, wet day in june (when the weather is usually hot and dry), does that mean the region’s climate is changing?

No, this does not mean that the climate of the region is changing. The climate of a region is the behavior of the atmosphere over extended periods of time. The climate of Phoenix, Arizona may be described as hot and dry; meanwhile, weather describes the conditions of the atmosphere for a shorter amount of time, such as for a day. Therefore, the weather for that day will be cool and wet, not the climate.
