The calendar still says March, but much of the Southwest is behaving like late June, and FOX Weather meteorologist Steve Bender is making clear that this is not some ordinary warm spell that people can laugh off with shorts, sunscreen, and a cold drink.
In his latest forecast, Bender describes an extreme heat wave gripping a huge stretch of the region, one that is already breaking daily and monthly records and appears ready to intensify further as the week goes on. His warning is not just about how hot the afternoons get, but about how broad, how early, and how stubborn this event is becoming.
That combination is what makes this one stand out.
Spring has barely arrived, yet parts of the Southwest are already seeing temperatures 20 to 35 degrees above average, with a strong high-pressure dome continuing to build overhead instead of easing off. Bender says more than 40 million people are under this broader heat threat, and over the next week, more than 1,000 record highs could fall across eight states.
That is not a quirky weather headline. That is a serious, prolonged heat event landing before many people have mentally, physically, or practically adjusted for summer conditions.
Records Are Already Falling, And The Peak Is Still Ahead
Steve Bender says this heat wave is not being measured only by one dramatic number in one desert city. It is being measured by how many different kinds of records are falling all at once.
He notes that the Southwest is not just seeing daily records break. Monthly records are also being challenged, and in some places the hottest March temperatures ever recorded are now in danger. That is what turns an unusually warm week into something closer to a historic event.
Bender points to Phoenix as one of the clearest examples. The city hit 100 degrees, which he says is the earliest on record that Phoenix has ever reached that mark. What makes that even more striking is the comparison to normal. This time of year, Phoenix should typically be in the upper 70s, not flirting with peak-summer heat.
He says that means the city is running roughly 20 to 25 degrees above average, and not for just one isolated afternoon. The pattern driving this surge is strengthening, not weakening, which is why he says the heat will continue to build deeper into the end of the week.
That is the part people sometimes miss with early-season extremes. A lot of folks hear “record heat” and picture one bad day. Bender is talking about a multi-day event with momentum behind it, the kind that becomes more dangerous because it lingers.
Las Vegas, Palm Springs, And The Desert Hot Spots Are Leading The Charge
Bender also spotlights Las Vegas, which crossed 90 degrees for the first time in 2026, and did so with enough time left in the day for the temperature to keep climbing afterward. That may not sound as dramatic as Phoenix hitting 100, but in the context of the broader pattern it matters because it shows how many cities are entering territory they had not yet touched this year.
Then there is inland California, where Bender says the heat is becoming even more eye-catching.
He points to Thermal and Palm Springs, which surged to around 106 degrees, and says the region is not just threatening state records but could even make a run at the national U.S. temperature record for the month of March. He specifically frames this as one of the numbers FOX Weather will be watching closely because the biggest daily highs may not even have all arrived yet.
That is a remarkable thing to say in the third week of March.
Usually, this time of year, people in those areas expect warmth, maybe even a hot afternoon or two. But there is a huge difference between warm spring weather and a setup that starts putting national March records on the table. Once that happens, the conversation changes from “nice out” to “pay attention.”
And Bender’s broader point is that the scale of this heat is what makes it so unusual. It is not a one-city event. It is spread out across a major section of the Southwest, and that makes the risk more complicated.
California Is Getting Hit Harder And Farther North Than Many Expect
One of the strongest parts of Bender’s report is the way he explains that this is not just a classic desert heat story limited to the obvious hot spots.
He says Anaheim and Santa Ana reached 100 degrees, something they had never done before in the month of March. That alone tells you how abnormal this air mass is, because those are not the first cities most people picture when they think of extreme desert heat.
Bender also highlights San Francisco, where the observed high reached 85 degrees, tying a record that went back 74 years, to 1952. Farther north, he points to Redding, which climbed to 92 degrees, good for the second-warmest March day on record there and, even more strikingly, the earliest 90-degree day ever observed.
That northern reach matters.
When heat records begin falling not just in the low desert but also along the coast and into the southern Cascades, it shows how broad the ridge really is. It also means people in places that are not psychologically “summer ready” are suddenly dealing with heat more typical of much later in the year.
Bender underscores that by reminding viewers how early this is. The region is getting the feel of the heart of summer before spring has even fully settled in, and that timing can catch people off guard in a dangerous way. Heat is always serious, but it becomes more serious when it arrives before routines, work schedules, and public habits have adjusted.
This Is Not Just A Vacation Story – It Is A Worker Story
One of the better points in Bender’s segment is that he does not let the visuals of sunny skies and happy tourists flatten what is really happening.
He includes interviews from San Jose, where visitors from out of state say the warmth feels great, almost like an early taste of summer. One woman says it is “awesome,” while another visitor jokes that she had to go buy more sunscreen. Those reactions make sense. When you are on vacation, hot sunshine can feel like a perk.
But Bender immediately contrasts that with the reality for people who have to work in it.
He points to outdoor crews trying to stay safe by taking more breaks, drinking water, and loading up on electrolytes, and he emphasizes that this is not a one-day inconvenience. For many workers, this is the reality they have to live in day after day over the next stretch, especially with extreme heat alerts already in place in areas from Las Vegas down toward Phoenix.
That distinction is important, and honestly it often gets lost in weather coverage.
There is a big difference between stepping outside for a sightseeing afternoon and spending eight hours on pavement, in a construction zone, or under direct sun without much natural shade. Bender is right to stress that because extreme heat in March can fool people into thinking it is less threatening than the same temperatures in July. The body does not really care what month it is if the heat is intense enough.
The Longevity Of The Heat May Be The Most Dangerous Part
Bender says the peak of this event is not just about the highest number that flashes on one afternoon. It is also about the longevity of the heat wave, which he says is often what catches people off guard.
That feels like the key point in the whole forecast.
A hot day can be managed. A long run of hot days starts to change behavior, strain infrastructure, increase fire risk in some places, and wear down the body, especially for the elderly, outdoor workers, travelers, and anyone without reliable cooling. When a heat wave keeps rolling without much relief, small bad decisions start to add up.
Bender’s forecast suggests that is exactly the kind of pattern unfolding here. The strong high pressure over the region is not simply parking in place for one burst and then moving on. It is strengthening enough to keep feeding the heat across a wide area, which means the records are not just falling once. They are being challenged again and again as the week continues.
That is why he warns that people across this part of the country should not treat the event casually just because the skies are blue and the scenery is beautiful.
National Parks And Desert Travel Could Turn Risky Fast
Toward the end of the segment, Bender makes a point that feels especially worth repeating for anyone traveling through the Southwest.
He says people heading to national parks, particularly in the desert landscape, need to understand what they are walking into. Places like the Grand Canyon are not full of leafy shade and easy cooling spots. They are exposed, open, and sun-drenched for long stretches, which means even a scenic day trip can become dangerous if people underestimate the heat.
That warning matters because spring-break travel and early-season tourism often bring visitors into these places at exactly the wrong time mentally. Many are still thinking like it is spring, packing like it is spring, and planning like it is spring.
But Bender’s forecast says the region is already behaving like summer in ways that are not normal even for March in the Southwest.
The message is simple: bring more water than you think, plan for full sun, use sunscreen, and do not assume a pleasant morning means the afternoon will stay manageable.
A March Heat Wave That Looks More Like June
Steve Bender’s forecast paints a picture of a Southwest heat event that is not only intense, but historically early and wide-ranging enough to demand respect.
Phoenix hitting 100 so early, Las Vegas passing 90 for the first time this year, Palm Springs and Thermal racing into the 100s, San Francisco tying a record from the early 1950s, and Redding hitting an earliest-ever 90-degree day all point to the same conclusion: this is not normal spring warmth. It is a major atmospheric setup producing true heat-wave conditions across a huge swath of the West.
Bender’s phrase that this kind of heat can catch people off guard is probably the most important takeaway. March can trick people into thinking they still have time before dangerous heat arrives.
This year, at least across the Southwest, that time is already gone. The records are falling, the high pressure is still flexing, and the region is getting a hard reminder that summer-style weather does not always wait for summer to start.
