Best Time to Visit Las Vegas

Go in April or October. April runs 27.3°C / 81.1°F by day and 13.0°C / 55.4°F at night with 0.7mm of rain across zero rainy days; October is 27.9°C / 82.2°F and 14.4°C / 57.9°F with 18.2mm falling on a single day. Those are the only two months that give you pool-warm afternoons without the 40°C / 104°F wall that arrives in June and stays until September.

April and October: the two months that actually work

Las Vegas is a walking city disguised as a driving one. The Strip is about 6.8km end to end, casino-to-casino gaps are longer than they look from a map, and a single evening easily puts 12,000 steps on you. That makes the daytime high the number that decides your trip, not the scenery.

April sits at 27.3°C / 81.1°F. That is warm enough that the pool decks are open and full, cool enough that you can walk from the Bellagio to the Venetian at 2pm without arriving soaked. The 0.7mm of rain over zero rainy days is not a rounding trick — April 2025 essentially did not rain in Las Vegas. You do not need to pack a jacket for weather; you need one for the 13.0°C / 55.4°F night, which is a real 14-degree drop from the afternoon and catches people who left the hotel at 4pm in a tank top.

October is April's mirror, half a degree warmer by day at 27.9°C / 82.2°F and a degree warmer at night at 14.4°C / 57.9°F. Its 18.2mm of rain arriving on one day is worth reading correctly: that is a single afternoon or evening cell dumping most of an inch and then clearing, not a wet month. If it lands on your trip you lose two hours, not two days. Statistically you have roughly a 1-in-30 chance of that day being yours.

The practical difference between the two: October water is still holding summer heat, so pools and the outdoor lounges feel better than the air temperature suggests. April water is coming off a cold winter and hotel pools that are not heated feel sharper than 27°C air would imply.

June, July and August: the months to avoid

July averages a daily high of 40.7°C / 105.3°F. August is 40.6°C / 105.1°F. June is 39.2°C / 102.6°F. These are average highs, which means half the days beat them.

Dry heat is a real thing and it does help — sweat evaporates, so 40°C in Las Vegas is more tolerable than 33°C in Bangkok. But the marketing line hides what the numbers actually do to a trip. At 40.7°C the pavement radiates, the walk between two adjacent resorts becomes a decision rather than a stroll, and your day reorganises itself around indoor air conditioning. You will taxi or rideshare distances you would have walked in April. Budget for that.

The night numbers are the part people miss. July lows are 25.5°C / 77.9°F and August lows are 26.1°C / 79.0°F. The desert does not cool off at night in summer. Stepping outside at 11pm in August you are still in 26°C air, which means there is no evening window where walking the Strip is comfortable — there is just less sun. Compare that to January, where the day-to-night gap is 14.1°C down to 1.5°C.

August also carries 18.9mm of rain on one day. In the desert that arrives as a monsoon cell: sudden, hard, brief, sometimes enough to flood underpasses and stall traffic for an hour. It is not a reason to avoid August. The 40.6°C is.

The one honest argument for summer is money. Las Vegas discounts hard in July and August because demand collapses, so if a heavily discounted resort with a good pool is the whole point of your trip and you plan to be in water or air conditioning from 11am to 5pm, summer is defensible. Just go in knowing you are buying a pool trip, not a city trip.

Shoulder season: March, May, November and December

March is the strongest shoulder month. At 22.1°C / 71.8°F daytime and 9.1°C / 48.4°F at night, it is genuinely mild — long-sleeve weather in the evening, T-shirt weather at midday. Its 5.8mm of rain spread over 3 days means light, forgettable drizzle rather than downpours. The tradeoff is that 22°C is under the pool threshold for most people, so the outdoor pool scene is quiet or partially closed.

May at 32.7°C / 90.9°F is the last month before the heat becomes hostile, and it is a good one if you want pool weather. Nights at 18.1°C / 64.6°F are the most comfortable of the year for eating outdoors. The 18.8mm over 3 days is the wettest of the warm half of the year but still nothing that reshapes a trip.

November looks tempting on temperature — 21.2°C / 70.2°F by day, 9.8°C / 49.6°F at night — but it carries 57.1mm of rain over 6 days, which is by a wide margin the wettest month of the year. That is roughly 9.5mm per rainy day and a 1-in-5 chance that any given day of your trip has rain in it. In a city where a lot of the experience is outdoors between buildings, six wet days out of thirty matters. November is the cheapest of the mild months for a reason.

December, at 17.1°C / 62.8°F and 5.5°C / 41.9°F, with 21.5mm over 4 days, is a jacket-and-indoors trip. Rates drop mid-month, then spike hard for New Year's Eve, which is one of the busiest nights of the Las Vegas year.

What each season actually means for your day

Winter (December–February). January is the coldest month at 14.1°C / 57.4°F daytime and 1.5°C / 34.7°F overnight — that low is near freezing, and standing outside at 11pm waiting for a car is genuinely cold. Pack a proper jacket, not a windbreaker. January had 0.0mm of rain over zero days, so it is dry and clear, just cold. February jumps to 20.0°C / 68.0°F, one of the biggest month-to-month swings on the table, and is the point at which outdoor dining becomes pleasant again. Winter is show-and-restaurant season. Pools are closed or heated-and-empty.

Spring (March–May). Layers. You will leave the hotel at 27.3°C in April and come back at 13.0°C. Daypack with a light jacket, and sunglasses that stay on — the desert sun at this angle is harsh even when the air is mild. Red Rock Canyon and the Hoover Dam day trips are at their best here; hiking in April at 27°C is fine, hiking in July at 40.7°C is a rescue call.

Summer (June–August). Pool clothes, a refillable bottle you actually refill, and a schedule built around avoiding 12pm–4pm outdoors. Sunscreen matters more than you think at this latitude and altitude. If you are driving to the Grand Canyon or Death Valley, carry more water than feels sensible.

Autumn (September–November). September at 34.7°C / 94.5°F is still hot but has broken from the summer peak and nights at 21.8°C / 71.2°F are finally pleasant. October is the sweet spot. November needs a rain layer for the first time all year.

FAQ

Is it too hot to visit Las Vegas in July?

July averages 40.7°C / 105.3°F and drops only to 25.5°C / 77.9°F overnight, so there is no cool part of the day. It is survivable and it is cheap, but you will spend the trip indoors or in water and you will pay for short rides you would otherwise walk. If you can move your dates to April or October, do.

When is the cheapest time to visit Las Vegas?

Rates track weather closely here. July and August are cheapest because 40.6–40.7°C / 105.1–105.3°F drives demand away. Among the comfortable months, November is the cheapest — but it carries 57.1mm of rain across 6 days, the wettest month of the year. March, at 22.1°C / 71.8°F with only 5.8mm of rain, is usually the best compromise between price and weather.

What should I pack for Las Vegas?

Layers, in every month except deep summer. The desert temperature swing is real: April goes from 27.3°C / 81.1°F to 13.0°C / 55.4°F, and January from 14.1°C / 57.4°F to 1.5°C / 34.7°F. Add comfortable walking shoes — the Strip's distances are much longer than they look — plus sunscreen and a water bottle year-round. A rain layer is only worth the space in November and December.

Does it rain much in Las Vegas?

Almost never, with one exception. Seven of the twelve months see 0 or 1 rainy days, and January and April recorded zero. When rain does come in warm months it arrives as a single hard cell — August's 18.9mm and October's 18.2mm each fell on one day, meaning a short downpour and then clearing skies, not an overcast day. The exception is November, whose 57.1mm across 6 days is more rain than the previous five months combined.
