How We Define the Best Time to Visit Las Vegas
There is no single answer to the best time to visit Las Vegas. A visitor who plans to walk the Strip, hike nearby canyons or sit by a pool each has a different ideal season. We use temperature as the measure here because it is the one factor we could source from an official agency.
The data comes from the National Weather Service Las Vegas office, which lists normal highs, lows and records for the 1991 to 2020 period. Normals are averages over time, so any single year can be hotter or cooler.
Las Vegas Temperatures by Month
The table shows normal average highs and lows in degrees Fahrenheit, plus the record high for each month, from the National Weather Service. The average temperature column comes from its warmest and coldest averages file.
| Month | Normal high | Normal low | Average | Record high |
|---|---|---|---|---|
| January | 58.5 | 40.5 | 49.5 | 77 |
| February | 62.9 | 44.1 | 53.5 | 87 |
| March | 71.1 | 50.5 | 60.8 | 98 |
| April | 78.5 | 56.9 | 67.7 | 99 |
| May | 88.5 | 66.1 | 77.3 | 109 |
| June | 99.4 | 75.8 | 87.6 | 117 |
| July | 104.5 | 82.0 | 93.2 | 120 |
| August | 102.8 | 80.6 | 91.7 | 116 |

| November | 67.1 | 47.3 | 57.2 | 87 |
| December | 56.9 | 39.6 | 48.2 | 78 |
The annual normal high is 80.5 and the annual normal low is 59.6. The yearly average is 70.1 degrees. July is the hottest month by normal average temperature at 93.2, and December is the coldest at 48.2, though January has the lowest normal high at 58.5.
Spring: March to May
Spring is an obvious candidate for the best time to visit Las Vegas for outdoor plans. Normal highs rise from 71.1 in March to 78.5 in April and 88.5 in May.
Heat can arrive early. The record high for March is 98, set on March 25, 2026, and April has reached 99 as recently as 2020. Spring is not always mild, so check the forecast.
Summer: June to August
Summer is the hottest season. Normal highs are 99.4 in June, 104.5 in July and 102.8 in August. Normal lows are 75.8, 82.0 and 80.6, so nights stay warm.
The National Weather Service lists a record of 117 for June, 120 for July and 116 for August. If you visit in summer, the best time to visit Las Vegas for comfort is early morning or evening, which is our suggestion. Plan indoor activities in the afternoon.
For heat safety, drink water often and take breaks in shade or air conditioning. The National Park Service tells visitors to Zion to watch for heat stress, and the same caution applies to a summer day in the city. That heat advice is general, and it is not from the weather service page.
Fall: September to November
September is still hot, with a normal high of 94.9. October cools to 81.2, and November to 67.1.
Fall is another popular choice for the best time to visit Las Vegas if you prefer comfortable days. The record highs are still high, at 114 in September and 103 in October, so a warm spell is possible.
Winter: December to February
Winter is cooler but not freezing during the day. Normal highs are 56.9 in December, 58.5 in January and 62.9 in February. Normal lows are 39.6, 40.5 and 44.1, so evenings can feel cold.
Whether winter is the best time to visit Las Vegas depends on how you feel about cool evenings. If you plan to be outside at night, pack layers. Winter can be a comfortable time to explore on foot, although the sources we read do not cover crowds or prices.
How Much Do Temperatures Swing Each Day?
By our arithmetic from the National Weather Service table, the gap runs from about 17 degrees in December to about 24 degrees in June.
That matters for packing in any season. A comfortable afternoon can turn cool after dark, especially from November to March when normal lows sit between about 40 and 50 degrees.
Packing for the Best Time to Visit Las Vegas
These suggestions are ours and not from the weather service. In summer, bring light clothing, sun protection and a wrap for strongly air-conditioned indoor spaces. In spring and fall, pack layers. In winter, bring a warm jacket for evenings.
Bring a refillable water bottle year-round and use it often.

Planning Around the Heat
If your dates fall in June, July or August, plan the best time to visit Las Vegas around the cooler parts of the day. Our suggestion is to do outdoor activities early, rest indoors in the afternoon and go out again after sunset.
Remember that the normal low in July is 82.0, so nights stay warm too. Travel with water, wear light clothing and allow breaks. If you or someone in your group feels dizzy or ill from the heat, move to a cool place and seek medical help if symptoms continue.
What the Weather Data Cannot Tell You
The temperature normals do not tell you how busy the city is, what hotels cost or which conventions and events will be in town. Those factors can matter more than weather for the best time to visit Las Vegas.
Check event calendars and compare prices for your dates. Our guide on how to find cheap flights can help with airfare, and our guide to how to plan a road trip on a budget covers driving costs.
Planning a Longer Southwest Trip
The best time to visit Las Vegas can change if your visit is part of a bigger trip, since weather elsewhere differs.

Mistakes to Avoid

Who Should Be Extra Careful
Heat matters for the best time to visit Las Vegas.
