Question

Context: Trying to plan a van trip thru Arizona/New Mexico in late Dec/early Jan, but concerned about snow and cold temps.

- What regions/cities/areas typically get snow that we shoud avoid.

- Where should we go for warmer weather/not freezing.

Answer

Planning a winter campervan road trip through Arizona and New Mexico in late December/early January can be very rewarding, but you’ll need to plan carefully for cold temperatures, potential snow, and comfort in a rental van. Here’s a detailed guide to help you maximize outdoor enjoyment while minimizing risks.

Winter Weather Overview:

Arizona and New Mexico have a wide range of winter climates. Low deserts (like Phoenix, Tucson, and southern NM) are usually mild, while higher elevations (Sedona, Flagstaff, northern NM) can be cold with snow.

Arizona: Sedona and Flagstaff can get snow, especially Flagstaff. Phoenix, Tucson, and Saguaro NP area are generally mild with daytime highs 55–65°F (13–18°C) and cool nights around 35–40°F (1–4°C).
New Mexico: Northern NM (Santa Fe, Taos) often sees snow and cold weather; southern NM (Las Cruces, Carlsbad) is milder and much more suitable for outdoor activities in winter.

Recommended Route & Destinations:

Since you want to avoid freezing temperatures and snow, consider a south-to-north loop starting in warmer areas first:

Tucson & Saguaro National Park – great for hiking among iconic cacti; winter days are mild and nights manageable.
Southern New Mexico – White Sands National Park, Carlsbad Caverns National Park, and Las Cruces for mild temperatures and scenic landscapes.
Sedona – beautiful red rock hikes, but check forecasts for snow. Can combine with a detour to Jerome or Oak Creek Canyon.
Flagstaff – only if you’re equipped for cold and potential snow; otherwise, consider skipping it or limiting your time.
Optional: Petrified Forest National Park – desert environment, usually snow-free in winter.

Tips for Winter Van Life:

Check weather forecasts daily, especially for higher elevations.
Insulate your van and consider sleeping bags rated for near-freezing temperatures.
Use a small portable propane heater safely, if allowed by the rental company.
Carry extra water in insulated containers to prevent freezing.
Plan campsites with access to restrooms/showers in case of very cold nights.
Fill your tank whenever possible – gas stations may be sparse in rural areas.

Regions to Avoid or Approach with Caution:

Flagstaff, Prescott, Payson – higher elevation towns can have snow and icy roads.
Northern New Mexico – Santa Fe, Taos, and the mountains around these areas.

Regions for Milder Weather:

Southern Arizona – Tucson, Phoenix metro (if you want to explore urban parks or hike nearby deserts).
Saguaro National Park – mild winter temperatures, excellent desert hikes.
Southern New Mexico – Las Cruces, White Sands, Carlsbad Caverns.

Overall, focus on southern Arizona and southern New Mexico for the warmest and most comfortable outdoor experience. Sedona can be included but plan for early mornings and evenings to be chilly, and check snow forecasts. With careful planning, winter van life can be very enjoyable in these regions, allowing for hiking, sightseeing, and exploring unique desert landscapes without the hassles of snow or freezing conditions.
