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.
