Climate Zone
Hot & Arid
Covers the desert Southwest (Arizona, Nevada, New Mexico), defined by low humidity, intense sun, and wide day-to-night temperature swings. Pool season runs nearly year-round in the lowest-elevation cities, and heating can extend swimmable months even further. The #1 maintenance consideration is evaporation and water loss: dry air and high heat pull water down fast, so refill frequency and water cost matter more here than in almost any other zone.
