Phoenix Faces Extreme Heat and Monsoon Challenges
Phoenix, Arizona, experiences extreme summer heat and dramatic monsoon weather patterns. Summer temperatures often exceed 110°F (43°C), with a record high of 122°F (50°C) set in 1990. The North American Monsoon season, from July to September, brings short but intense storms, including haboobs—massive dust storms caused by thunderstorm downdrafts. These storms reduce visibility to zero and can cause flash flooding in low-lying areas. The monsoon also provides much-needed rainfall, replenishing water supplies and supporting desert ecosystems (source: DEEPER, 2026-09-07).
