About weather on the Arizona Trail

Arizona Trail (Mexico Border to Stateline Trailhead) crosses low Sonoran desert, isolated mountain ranges, the Mogollon Rim, the Grand Canyon, and the Kaibab Plateau. March and October often align with manageable desert heat in the south and lingering cold or snow risk in the north, balancing progress across the elevation bands. Starting too late brings hot, dry desert sections; starting too early or finishing late increases the likelihood of snow, icy mornings, hard frosts, and short days on the northern plateaus.

• Winter brings mild, occasionally showery deserts contrasted with wintry central and northern highlands, frequent snow, subfreezing nights, and alternating clear, cloudy, and stormy spells.
• Spring transitions from warm, showery deserts to lingering high‑country snow and freezing nights, then drier, sunnier days with southern heat and brief mountain downpours.
• Summer features extreme southern heat, frequent afternoon thunderstorms, heavy downpours, and milder, showery high plateaus alternating between sunny breaks and building clouds.
• Autumn begins with southern monsoon showers, transitions to warm deserts and chilly highlands, then brings frosts, early snow, and recurring northern storms.
