Mid-April to early June, and late September to late October (shoulder seasons). WeatherSpark identifies these windows as optimal for outdoor tourist activities: temperatures are warm but not oppressive (not the brutal 105°F+ of summer), crowds are thinner than peak winter, and rates at resorts and spas drop significantly versus the Nov–Mar peak. October especially offers ideal hiking and golf temperatures with cooler desert nights
