The best time to visit Las Vegas depends on three variables: weather tolerance, budget, and whether any specific event or trade show is running that week. There's no single right answer — but there are clear sweet spots for price-plus-weather travelers and clear weeks to avoid.
Here's the month-by-month breakdown.
The Short Answer
Late March through early May, and most of October. Those are the two sweet-spot windows where daytime highs sit in the 70s-80s, pool season is active (or just starting), and hotel rates haven't spiked into convention territory.
Avoid: July-August if heat is a dealbreaker, and any CES (January), SEMA (November), or World of Concrete (late January) weekend if rate-shopping matters.
January – March
January: daytime highs 55-65°F. CES lands first week — trade show attendance of 140,000+ pushes hotel rates 3-5x normal on 4-5 specific nights. Outside CES, January is the cheapest month of the year. AVN Expo and World of Concrete occupy mid-to-late January and cause similar rate spikes.
February: NFL playoff season draws sports travelers to sportsbooks. MAGIC Fashion Trade Show mid-month. Weather mild but evenings cold. Chinese New Year runs January or February and the Bellagio Conservatory lands its Lunar New Year installation.
March: March Madness first and second weekend packs sportsbooks. Weather warms steadily — highs in the 70s by month-end. Spring Break pushes rates mid-March. This is when pool decks start re-opening.
April – June
April: the start of the sweet spot. Daytime highs 75-85°F, comfortable evenings, pool decks fully operational. The Viva Las Vegas Rockabilly Weekend and Great Vegas Festival of Beer run mid-month. No major conventions.
May: still shoulder-season weather (80s daytime) but EDC Las Vegas hits mid-May with 500,000+ attendees, pushing rates city-wide for that specific weekend. WSOP opens end of May and runs through July. Helldorado Days is the old-Vegas Western festival first week.
June: genuinely hot (90s daytime). Pool decks peaking. WSOP bringing serious poker-player volume to Paris/Horseshoe. Hotel rates soften mid-week.
July – August
Highest heat of the year — 105°F+ daytime baseline, nights in the 80s. Some July records hit 117°F.
Cheapest month for standard hotel rooms outside of convention weeks. Cheapest pool cabana rates of the year. Real outdoor activity is restricted to sunrise windows; after 10 AM hiking at Red Rock or Valley of Fire is dangerous.
Monsoon season runs July-August. Expect afternoon thunderstorm risk on 15-30% of days. Flash flood warnings can close roads to Valley of Fire and sections of Red Rock.
Best for: pool-focused trips, shopping trips (Forum Shops and Fashion Show are air-conditioned), show-heavy trips that don't require daytime outdoor activity.
September – October
September: cools off mid-month. iHeartRadio Music Festival third week of September at T-Mobile Arena draws pop-music crowds.
October: the second sweet-spot window. Daytime highs 75-90°F across the month, cool evenings, minimal monsoon risk. NASCAR South Point 400 playoff race early October. Las Vegas Pride and VGK home opener also land this window.
Hotel rates drop compared to summer; days are more pleasant. For most travelers without kids tied to a school calendar, October is the single best month.
November – December
November: pleasant weather (60s-70s), shorter days. SEMA Show first week — second-largest trade show in Vegas behind CES; rate spike. F1 Las Vegas Grand Prix mid-November — night race closes the Strip to cars for 3 days and pushes Strip hotel rates into four figures per night.
December: NFR first 10 days pushes rates at Strip-adjacent hotels. Cowboy Christmas Gift Show runs concurrently at the Convention Center. Mid-December (the 15th-22nd) is the cheapest week. NYE Strip fireworks on December 31 pushes rates to annual peak.
Pitfalls to Avoid
The single most common mistake is booking a Vegas weekend without checking the convention calendar first. CES (Jan), SEMA (Nov), World of Concrete (Jan), MAGIC Fashion (Feb), and NAB (April) can 3x-5x hotel rates on specific nights.
Check the Las Vegas Convention and Visitors Authority calendar before booking. A Tuesday-Thursday non-convention week often costs half what a Friday-Saturday convention weekend costs for the same hotel.
For most travelers: book October for perfect weather and thin convention calendar, late April for spring pool energy and shoulder rates, or mid-December for holiday decor and lower weekday rates just before NYE spikes.
