LAS VEGAS, Nev. (FOX5) – The spring heat is on across Southern Nevada this week. Wednesday is the hottest day of the stretch, with our first 90° day of 2025 in the forecast this afternoon.
If it feels like we’re talking about the 90s a little early this year, you’re not imagining it. High temperatures in the mid-70s are more typical in late March. The average first 90° of the year in Las Vegas is April 15th. The earliest we’ve seen a 90° day in past years was on March 13th, 2007. The latest we’ve waited for the 90s was back in 1983 on May 21st.
With the heat this week, one common question in the FOX5 First Alert Weather Center is, “Does this mean summer will be hotter than normal?” The short answer is no. No strong scientific evidence suggests hot spring weather will cause a hotter summer in Las Vegas.
We can look back to 2022 when March 26th brought us a daily record high of 93°. That spring was hotter than average but led to summer temperatures that were close to normal.
We’ve also seen cooler-than-average springs, like in 2020, leading to higher-than-average summer temperatures.
Since we’re talking about our first 90° day, you might be curious about when we’ll see our first 100° day. We typically see our first triple-digit day in Las Vegas in May. The earliest 100° day on record is May 1st, and our average first 100° day in Las Vegas is May 24th.
