Las Vegas Weather Forecast

For the most pleasant weather, visit Las Vegas in the spring (March to May) or fall (September to November). During these months, you'll enjoy warm, sunny days perfect for exploring the Strip and nearby natural attractions without the intense heat of the summer.

Summer in Las Vegas is extremely hot. Temperatures frequently exceed 100°F (38°C) from June to August, and can even reach 115°F (46°C) or higher. The good news is that the humidity is very low, but it's a dry heat that requires constant hydration.

Yes, it does. While known for its heat, Las Vegas is in the desert, which means temperatures can drop significantly, especially at night. Winter days (December to February) are mild, with highs around 55-65°F (13-18°C), but nighttime lows can dip to freezing or below.

Most resort pools open in March and close in October, but this can vary. The prime pool season is from May to September when the water is warm and the sun is shining. Some hotels have year-round heated pools, so it's best to check with your resort if visiting in the cooler months.

Rain is rare in Las Vegas, which averages only about 4 inches of precipitation per year. The most likely time to see rain is during the summer "monsoon" season (July-September) when brief, heavy thunderstorms can occur, sometimes causing localized flash floods.

Packing depends on the season. For summer, bring light, breathable clothing, swimwear, a hat, and strong sunscreen. For winter, pack layers: sweaters, long pants, and a medium jacket. For spring and fall, a mix of shorts, pants, and a light jacket is perfect. No matter the season, always bring comfortable walking shoes and a light sweater or jacket, as casinos and restaurants are heavily air-conditioned.

Las Vegas has extremely low humidity year-round, typically between 10-30%. This creates a dry climate where the heat feels more intense than in humid areas with similar temperatures. The low humidity also means you'll need to stay hydrated, especially during outdoor activities.

Snow is extremely rare in Las Vegas itself, with measurable snowfall occurring only about once every 10-15 years. However, the nearby mountains do get snow in winter. If you're visiting during winter and want to see snow, consider a day trip to nearby ski resorts like Lee Canyon.

Weather significantly impacts outdoor activities. Summer heat makes hiking and outdoor exploration challenging, so focus on early mornings or evenings. Spring and fall are ideal for outdoor adventures like Red Rock Canyon hiking or golfing. Winter is perfect for indoor activities, though some outdoor attractions remain enjoyable during mild winter days.

The UV index in Las Vegas is extremely high year-round, often reaching 8-11+ (very high to extreme) during summer months. Even in winter, it can be 4-6. Always wear strong SPF 30+ sunscreen, UV-blocking sunglasses, and protective clothing.

Weather-related cancellations are rare in Las Vegas due to the dry climate. Shows and entertainment rarely cancel due to weather. However, outdoor events, helicopter tours, or activities at Red Rock Canyon might be affected by extreme heat, high winds, or rare rainstorms.

Temperature swings are dramatic in the desert. Daytime highs can drop 30-40°F (17-22°C) by night. For example, a 100°F day can cool to 70°F by evening. This is why layering is essential.

Spring (March-May) and fall (September-November) offer the best golfing weather with mild temperatures (70-85°F/21-29°C), low humidity, and plenty of sunshine.

Las Vegas has excellent flying weather most of the year. Summer thunderstorms can occasionally cause delays, and winter high winds might affect smaller aircraft. However, the airport rarely experiences significant weather-related disruptions.

Nevada has wildfire seasons, typically May-October, and smoke can occasionally affect air quality in Las Vegas. While the city itself is rarely directly threatened, winds can carry smoke from fires in surrounding areas. Check air quality forecasts before your trip.
