Las Vegas, Nevada – Memorial Day travelers in southern Nevada should brace for intense heat as Las Vegas climbs to 96°F Monday and breaks 100°F by midweek. Holiday drivers on I-15 and I-515 should expect sun-glare delays and elevated engine stress in extended traffic.
According to the National Weather Service, Sunday will be sunny with light south winds and a high near 94°F. By Memorial Day, breezes pick up to 18 mph with gusts as high as 28 mph in the afternoon. Temperatures will hover near 96°F under mostly sunny skies.
Hot Weather Safety: Hydrate frequently, avoid outdoor work between 1–5 p.m., and never leave pets or kids in parked vehicles. Locals and tourists alike should prepare for prolonged heat exposure, especially along the Strip and surrounding neighborhoods like Paradise and Summerlin.
Looking ahead, the high climbs again Tuesday to 96°F before cracking 100°F Wednesday and Thursday. Overnight lows remain in the low to mid-70s, offering little relief. Winds diminish midweek but return slightly Thursday with steady sun.
By Friday, the heat intensifies further — reaching 102°F — marking a definitive start to summer conditions in the Las Vegas Valley. No precipitation is expected, and skies remain clear throughout the five-day stretch.
Prepare now: Limit midday activity, check cooling systems, and monitor vulnerable residents. This extended period of dry, sunny heat will increase fire danger across Clark County.
