Packing recommendations depend on the season of your visit. Based on the climate data, pack lightweight, breathable clothing if visiting during the warm months (July is hottest at 35.6°C). For cooler months, bring layers and a warm jacket (January averages 9.0°C). A waterproof jacket or umbrella is recommended year-round as Las Vegas receives 109.0mm of annual precipitation. Sun protection is important, especially during months with high UV index.
Las Vegas tricks you with air conditioning. I stepped off the plane in July at 42°C and the terminal was 18°C — the shock is real. Pack layers for the casinos, sunscreen for outside, and accept you'll move between climate zones every 30 minutes. June-August is genuinely dangerous outside; plan pool mornings, indoor afternoons. The sweet spots are March-April and October-November: 22-26°C, perfect for hiking Red Rock. Skip December-February unless you love 12°C days and 4°C nights. Always carry water — desert dehydration sneaks up. And lip balm. Always lip balm.
