Prolonged exposure to intense UV radiation can cause some natural stones to fade or change color over time. Selecting stones with high UV stability, such as granite or certain sandstones, is important for maintaining the aesthetic appeal of outdoor installations in arid climates.

Natural Stone Arid Climate Guide
Arid climates, typical of the Southwest USA, are characterized by intense heat, low humidity, and high levels of ultraviolet (UV) radiation. These conditions require natural stone selections that can withstand extreme temperature fluctuations, resist fading from sun exposure, and remain comfortable underfoot in scorching conditions.
In regions with scorching daytime temperatures, the thermal properties of the stone are a critical consideration. Lighter-colored stones and specific types like travertine and limestone reflect more solar radiation and retain less heat, making them significantly more comfortable for barefoot use compared to darker, denser stones.
Arid climates often feature hot days and cool nights. This rapid temperature change causes thermal expansion and contraction within the stone. Proper installation techniques, including the use of flexible mortars and adequate expansion joints, are essential to mitigate the stress caused by these fluctuations and prevent structural damage like cracking.
The prevalence of windblown dust and sand in desert environments can act as an abrasive on stone surfaces. Choosing stones with adequate hardness and maintaining a regular cleaning schedule to remove abrasive particles will help preserve the stone's finish and prevent premature wear.
