Warm days and cool nights
Fall is an excellent time for visiting Phoenix, AZ. The spring are goo times to visit too. This is because the days are generally warm and the evening cool. The sunrises over the cool air mass that settles over the valley Phoenix is situated in every evening. The suns warm rays quickly warm the air to a comfortable temperature. Sunrise may see the temperatures being cool, in the 50′s, but the days warm rapidly into the 70′s to 80′s and occasionally the 90′s. The day temperatures and clear sunny skis make for a perfect place for out door living. If you like to sit out side and read, sleep in the sun, hike, bike, run or play sports the weather is perfect for that. As the sun goes down the air cools off quickly in the desert. It can become cool enough for a jacket as soon as the sun leaves the skies. This is because of thermal cooling. The dry air and clear skies do not hold the heat in and so it goes right up into the atmosphere and out to space. Evenings are beautiful sometimes with warm desert breezes blowing through the cool air. Here is the perfect weather in fall and spring. The winter is cooler and still nice. The days generally are in the 50′s to upper 60′s with cooler nights. Nights can get down to freezing occasionally and briefly. The days warm up not quiet as quickly as the rest of the year because the sunlight is not as strong. The sun is low in the sky and cooler at this time of year. The summer is very very hot in Phoenix. In the heart of the summer the sun rise temperature can be in the upper 80′s with day time highs getting into the hundred and teens. These days can be brutal. The sunlight very strong and searing. Mornings heat up quickly and temps will reach 100 before noon and can top out at 115 or more! This is a good time to head down under to Adelaide boutique hotels where it is winter and the temperatures are cooler then the summer in Phoenix.
