May Packing List for Las Vegas — What to Wear & Bring
May Las Vegas averages 88°F highs and 67°F lows — hot and almost rain-free. Pack lightweight clothing, SPF 50+, and a layer for casino air conditioning that runs 20°F cooler than the outdoor heat.
Averages 67–88°F, ~2 days of rain
Las Vegas May highs reach 88°F on the Strip — loose, breathable dresses in linen or moisture-wicking fabrics are the most comfortable option for extended outdoor time between casino properties.
Casino interiors at the Bellagio, Wynn, and ARIA run at 68°F — the 20°F temperature gap from May's 88°F outdoors creates jarring thermal shock that a packable layer prevents effectively.
Las Vegas dayclubs and pool venues like Encore Beach Club and Wet Republic open at full capacity in May — lightweight shorts and tops are the practical standard for all-day pool-to-Strip activities at 88°F.
May pool UV in Las Vegas reaches index 8–9 — a UPF 50+ rash guard or cover-up protects during extended Mandalay Bay or Wynn pool deck sessions where shade canopy coverage is limited.
Memorial Day weekend in late May is one of the biggest party weekends in Las Vegas — Omnia, Hakkasan, and XS Nightclub at Encore fill to capacity and enforce strict dress codes for their holiday events.
May Strip pavement at 88°F warms to surface temperatures well above air temperature — closed-toe breathable sneakers protect feet from hot concrete that becomes uncomfortable in open sandals from late morning onward.
Las Vegas May dayclubs and resort pools enforce no-shoe-on-deck rules — slides or slip-on sandals handle wet pool surfaces at Encore Beach Club and MGM Grand Pool without difficulty.
May evenings stay at 67°F on the outdoor Strip — strappy heeled sandals work for evening restaurant and show outings without the winter-boot warmth requirements of the cooler months.
Las Vegas May UV index reaches 8–9 — the desert valley at 2,001 ft elevation with very low humidity means UV exposure builds rapidly, and a wide-brim hat is the most effective single sun-protection item during all-day Strip walking.
Full-day May pool sessions in Las Vegas require full-body SPF 50+ — pool decks at Mandalay Bay and Wynn have limited shade canopy and UV index 9 produces burns in under 15 minutes on fair skin.
Las Vegas May sunshine is intense with nearly zero cloud cover — polarized lenses reduce glare off casino building glass and pool water to prevent eye fatigue during a 10-hour Strip day.
Las Vegas May dry heat at 88°F dehydrates faster than humid climates at the same temperature — water fountains are scarce between major Strip casino hotels and an insulated bottle keeps water cold for hours.
