Record-Breaking Heat

Phoenix holds some impressive records when it comes to heat.

  1. Monsoon season in Phoenix runs from June 15 to September 30. This period brings sudden, intense thunderstorms and heavy rainfall, providing much-needed relief from the heat.

Phoenix is a paradise for sun lovers.

  1. Phoenix enjoys around 300 sunny days per year. This makes it one of the sunniest cities in the world, perfect for those who love clear skies.

  2. The city has an average of 85% possible sunshine annually. This means that out of all the daylight hours in a year, 85% of them are sunny.

Unique Weather Phenomena

Phoenix's weather isn't just about heat and sun.

  1. Dust storms, known as haboobs, are common in Phoenix. These massive walls of dust can reduce visibility to near zero and are a dramatic sight to behold.

  2. Phoenix experiences temperature inversions during winter. Cold air gets trapped near the ground by a layer of warmer air above, leading to cooler temperatures and sometimes poor air quality.

Nighttime Relief

Even in a hot city, nights can bring some respite.

  1. Phoenix's desert climate means temperatures can drop significantly at night. While daytime highs can be extreme, nighttime lows often fall into the 70s or even 60s (°F), providing a break from the heat.

  2. The city's elevation of 1,086 feet (331 meters) helps moderate temperatures. Higher elevation compared to other desert areas means slightly cooler temperatures, especially at night.
