When is Las Vegas Cheapest to Visit?
Timing your trip right can save 25 to 40 percent on flights and hotels. Green months are cheapest, red months are most expensive.
Cheapest window
January–February. Save about 25–40% versus $$$$ Peak March; hotels track the same flight discounts in this $ Budget window, so flight and stay costs move together.
Book early regardless
March, April, and May sell out entirely when crowds hit High and pricing hits $$$$ Peak — book accommodation 3–4 months ahead regardless of budget, not only flights.
Best value sweet spot
January and November: great weather on this page (~14°C, 3 rain days) at $$ Mid pricing; Medium crowds still keep it from matching March’s sell-out rush.
Cheapest months to visit Las Vegas
January–February is the cheapest stretch to visit Las Vegas. $ Budget months on this page typically cut flights about 25–35% versus $$$$ Peak, with hotel rates moving in step rather than lagging. Averages sit near 14°C with roughly 3 rain days, so packing stays simple if you accept cooler or wetter days. The exception: festival or holiday spikes inside an otherwise cheap month can briefly push stays toward $$ Mid even when the band still reads $ Budget.
Most expensive months to visit Las Vegas
March, April, and May are the most expensive months to visit Las Vegas. $$$$ Peak and $$$ High rows align with High or Very High crowds and the 3–4 months booking lead already shown for sell-outs. Expect the 25–40% saving story to reverse here — you pay the premium the chart paints in red. Weather can still look strong (20°C, 2 rain days in March), which is why demand sticks. The exception: a shoulder week just outside the core peak label sometimes dips to $$$ High instead of full $$$$.
Best value months to visit Las Vegas
January and November offer the best value months to visit Las Vegas. Great-rated weather pairs with $$ Mid instead of $$$$ Peak, so you keep comfort without the full 25–40% penalty of peak pricing. January averages about 14°C with 3 rain days and Medium crowds — busy enough for open attractions, not yet March-style sell-outs. The exception: once a “value” month overlaps a major holiday cluster, lead times jump back toward 3–4 months even if the cost word has not flipped to $$$$ Peak.
