Las Vegas weather at a glance

• Las Vegas sits in the Mojave Desert, so **dry air is the default** and seasonal contrast is strong. Summer can feel closer to **extreme heat** than “just warm.”
• Rain is limited overall, but July–August can bring **monsoon-style thunderstorms** (short, intense, localized).
• Daily swings matter: planning for **midday vs evening** often prevents under- or overdressing.
• Indoors (casinos/hotels/malls) can run strong A/C, so a **thin layer** can be useful even in summer.
• Instead of a single answer, decide how much time you’ll spend outdoors in direct sun—everything else follows.

Dec · Jan · Feb

Winter (dry + cool nights): daytime is manageable, nights drop quickly

Avg low 1–6°C / high 12–16°C · Rainy days: 1–3 / ~5–25 mm

• Sunny afternoons can feel fine, but after sunset it cools fast.
• Wind can add a dry chill.
• Rain is uncommon, but when it happens it can feel colder.

A note for travelers

In winter, the biggest comfort gap often shows up during evening walks and show nights.

Mar · Apr · May

A note for travelers

Spring is straightforward outdoors, but sun exposure changes comfort quickly.

Jun · Jul · Aug · Sep

Summer (extreme heat + dry): outdoor exposure time is the main variable

Avg low 22–28°C / high 38–43°C (higher on heat waves) · Rainy days: 0–3 / ~0–15 mm (thunderstorms possible in Jul–Aug)

• Midday heat can feel intense even in dry air.
• Jul–Aug storms can be short and heavy; water can pool quickly on hard, dry ground.
• Indoors can feel cold from A/C—comfort can split between outside and inside.
