Climatic Conditions and Route Aesthetics

The route crosses three climate zones: Mediterranean (San Diego to Cajon Pass), arid desert (Mojave to Las Vegas), and high desert plateau (Utah). Best traveled in spring (March-May) or fall (September-November) to avoid extreme heat. Summer temperatures exceed 100°F in the Mojave; winter can bring snow on I-15 past Las Vegas.

• San Diego: 60-75°F year-round
• Mojave Desert: 90-110°F summer, 30-50°F winter
• Utah Plateau: 80-95°F summer, 20-40°F winter

Infrastructure Safety and Road Quality

I-15 is well-maintained with wide shoulders and clear signage. The segment through the Virgin River Gorge (Arizona/Utah border) has steep grades and sharp curves; use lower gears.
