Religion
As of 2005, the Apache Reservation in which Whiteriver is located showed a decrease from 73% traditional or atheist to 43%. The percent of the population who consider themselves "Christian" was then 53%.
Whiteriver has a Mediterranean climate (Köppen Csa/Csb) with summers featuring hot afternoons and mild mornings, and winters featuring comfortable afternoons and freezing mornings. Unlike most climates of its type, the summer drought only covers the first half of the hot season – monsoonal rains arrive in July and peak in August before falling off in September. During the dry early summer wildfires are however always a risk. The typical winter weather of mild days and freezing nights is sometimes interrupted by heavy rainfall or snowfall from Pacific storms, which bring an average of between 1.5 and 2 inches (38.1 and 50.8 mm) of precipitation each month, and a mean of 16.5 inches or 0.42 metres of snow – although the median annual snowfall is only 6.3 inches or 0.16 metres.
