Can't move the dates? How to avoid the worst crowds
- Need flexibility? The 19th–31st is the month's calmest stretch — the easiest window to move around in.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
Travelling on a busy day?
Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.
August weather in Las Vegas
Real heat — around 40°C / 104°F by day, so pace the afternoons and carry water, with rain on only about 3 days.
Worth booking the marquee sights ahead for the busy days, but you can keep the rest of the trip flexible.
