Southern Nevada faces a rapid warmup this week. Temperatures will climb into the upper 90s by Friday and hold steady through the weekend before reaching 100 degrees soon after.[1][2] This development arrives in early May, well ahead of the seasonal norm for the region.
Forecast Highlights the Quick Rise
Forecasters predict clear skies and intensifying heat across Las Vegas starting midweek. Wednesday highs will reach the upper 80s, setting the stage for Thursday’s jump to the low 90s.[3] By Friday, afternoon temperatures should hit 98 degrees, with similar readings expected Saturday and Sunday.
Such conditions mark a departure from recent milder days. Overnight lows will hover in the 70s, offering little relief.[1] The National Weather Service and private outlets align on this trajectory, pointing to a high-pressure system dominating the Desert Southwest.

- Thursday: 93 degrees
- Friday: 98 degrees
- Saturday: 99 degrees
- Sunday: Near 100 degrees
Earlier Than Typical for the Calendar
May in Las Vegas usually features highs starting around 85 degrees and gradually building toward 94 degrees by month’s end. Early May averages fall short of 90 degrees in most years.[4] Records show the earliest triple-digit reading occurred on May 1 in previous seasons, underscoring the rarity of this timing.

This year’s pattern echoes occasional hot starts but stands out amid broader monthly projections that include peaks up to 106 degrees later in May.[5] Long-range outlooks describe the period from May 1-6 as sunny and turning hot, aligning with current models.
Practical Steps Amid the Heat
Local officials have urged precautions as temperatures approach these levels earlier than expected. Residents and visitors should prioritize hydration and limit midday outdoor exposure.[6] The heat affects daily routines, from outdoor work to tourism along the Strip.
Energy demands may rise with air conditioning use, though no alerts have issued yet. Past early heat events prompted similar advisories, emphasizing acclimation challenges in spring.
As Las Vegas transitions toward summer conditions, this preview serves as a reminder of the region’s intense climate. Sustained warmth could follow, shaping plans through late spring.
