Considerations

Essential Tips

What to Pack

Layered clothing system - morning starts 16°C (61°F), afternoon reaches 32°C (90°F), requiring 3-4 clothing layers

SPF 50+ sunscreen minimum - UV index 9 at 1,200m (3,937 ft) elevation causes burns within 15 minutes

Wide-brimmed hat and sunglasses - high desert sun reflects off light-colored buildings and sand

Lightweight long pants for hiking - desert vegetation includes thorny cacti and sharp rocks

Closed-toe shoes with good grip - rocky terrain and potential snake encounters make sandals inappropriate

Light jacket or fleece for evenings - temperature drops to 16°C (61°F) after sunset

Reusable water bottle (1+ liter capacity) - dry air and sun cause rapid dehydration

Lip balm with SPF - 45% humidity and constant sun dry lips quickly

Dust mask or bandana - afternoon winds create dust storms, especially around construction areas

Portable phone charger - desert exploration areas have limited cell coverage and battery drain

Insider Knowledge

Visit outdoor attractions before 11am or after 4pm - afternoon winds reach 40-50 km/h (25-31 mph) making outdoor activities unpleasant

Local restaurants extend patio hours in May before summer heat arrives - best outdoor dining weather of the year

Gas up before heading to remote hiking areas - stations sparse beyond city limits and desert heat increases fuel consumption

Many locals take advantage of May weather for home projects and yard work - hardware stores busiest month, plan accordingly

Avoid These Mistakes

Underestimating UV exposure - thinking 32°C (90°F) isn't dangerous, but high altitude and desert conditions cause severe burns quickly

Not bringing layers - many visitors pack only for warm weather, then freeze during 16°C (61°F) mornings and evenings

Scheduling outdoor activities during peak wind hours (2-5pm) - dust and gusts make hiking and photography difficult
