What May actually feels like
May is Las Vegas's spring in lived terms: getting very hot. Most days feel cold, dry and often clear, with damper grey stretches arriving in bursts rather than settling in for the whole month Check the full climate tables below for monthly averages and packing cues.
The underestimated variable is the day–night temperature swing. It truncates outdoor evenings and pushes dinner earlier. Build one indoor spare block every day Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Early May often starts near 33°C while the final week trends toward 35°C. That 1° drift is enough to change coat weight mid-trip. Recheck the forecast before packing day seven Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Afternoons reach 34–35°C before an early sunset near the 14.5-hour daylight limit — plan open-air stops then.
Evenings cool quickly toward 27°C; shift to indoor dining and illuminated streets once the light drops.
